PATCH: auditd.c should handle nonselinux
by Elliot Peele 17 Jan '07

17 Jan '07

Currently isys/auditd.c will exit the installer if anaconda is built with USESELINUX=0. This patch should fix that. Elliot

distribution customization
by Bill Nottingham 16 Jan '07

16 Jan '07

One of the features we're working on for Fedora Core 7 is a framework to customize the distribution [1] without necessarily modifying the package set; this is needed as we're intending to target multiple 'spins' [2] of Fedora. Right now, what *currently* can be customized is: - anaconda splash screens and artwork (via product.img) - anaconda install classes (via product.img) - default package set (via comps.xml) - default groups selected in said package set (via installclasses) - repository selection (via installclass) What we *want* to be able to customize is: - default set of services to start rPath has sent a patch for chkconfig that allows for this; it works by writing override files for any service you want to change, and then running chkconfig. - sysctl settings Allow for different sets of defaults depending on app/workload. Server/desktop/router/etc. A simple implementation would just be to allow for /etc/sysctl.d/, and lay down files there, although there are integration issues there (see below.) So, there are three issues that need solved: 1) What other parameters do we want modifiable? I'm open to ideas. The one that hits me is 'anything that can be specified in kickstart'; reasonably, anything done there (well, excluding %post) should be able to be 1) made a default 2) made required. Potential implementations of this: a) Ship a kickstart file in the spin that's used by default. Pros: Easily expandable to do anything we want, through the use of %post Allows for future expansion and automatic support of any new anaconda features. Cons: If we want the concept of 'setting defaults' that the user of the spin can change, will need some reinterpretation of how kickstart is used inside of anaconda. Unless I've missed something. b) Embed this information in the install class Pros: Doesn't use kickstart Allows you change anaconda's UI, add/remove screens, etc. Cons: Deeply ties you to anaconda versions. More likely to break c) ??? 2) How do we package these modifications? a) A package containing whatever files are used to customize that pungi/whatever uses when building the image. Pros: Easy to drop whatever customizations onto the filesystem Cons: Well, either you have packages that Aren't Fedora in the spins, or you make someone go through and review them. b) Just a product.img, generated either as part of the spin, or passed to the tool to be put in the spin Pros: Easy to customize anaconda bits this way - infrastructure is already there. Cons: Awful for dropping any needed files on the filesystem. Unless you use kickstart %post, which is a dirty dirty hack. c) ???? Of course, you could argue that all this default setting, etc. belongs as part of a centralized configuration management and provisioning tool, such as cfengine or puppet. Not sure we really want to go down that road, though. Bill

Try to get a mirror list for network installs
by Ralf Ertzinger 16 Jan '07

16 Jan '07

Hi. When doing a network install (HTTP/FTP), could anaconda be persuaded to try and get a list of mirrors from somewhere (using a similar approach as the current yum mirrorlist, perhaps)? If this fails, or if the user wants to enter a private mirror, that's fine, and the mirror can be entered manually, but I think we ought to offer the user a list of mirrors to install from, if possible.

Logical volume goes crazy when anaconda exits
by Joel Andres Granados 15 Jan '07

15 Jan '07

I'm new to anaconda and to redhat. Been studying the code for a while now. My first objective was to execute the code from the files downloaded from cvs. (working with anaconda-11.1.2.27). I used the "/path/to/anaconda/anaconda --method:hd///dev:fstype:path" (/usr/sbin/anaconda --method=hd:///dev/mapper/VolGroup00-LogVol03:ext3:/mnt to be more exact) command. the firs error the anaconda reported was had something to do with the fstype. I started debuging the code and noticed that in the isys.py file on line 202 the fstype variable was passed as "ext3:" and not as "ext3" as I expected. So I manually changed the variable for the algorithm to continue. and it did. I have read the bugzilla for anaconda, not all of it but a lot of them, and have found no bug related to this matter. Is this even a bug? I might be doing something wrong. Any comments? The next error anaconda reported was on line on the rhel.py file in line 160 it stated that a key that was not present in the "self.taskMap" attribute was trying to be accessed. On debuging I noticed that the variable was set to a different value than those stated on line 32 of the same file (shown in quotations). I manually changed the variable and kept on going. I also notice that you might be able to modify this variable by modifying the system variable _PRODUCTPATH. I didnt try it but I saw a hint of this in the code. Initialization of taskMap: " taskMap = {'client' : [(N_("Office"), ["office"]), (N_("Multimedia"), ["graphics", "sound-and-video"])], 'server' : [(N_("Software Development"), ["development-libs", "development-tools", "gnome-software-development", "x-software-development"],), (N_("Web server"), ["web-server"])], 'workstation' : [(N_("Software Development"), ["development-libs", "development-tools", "gnome-software-development", "x-software-development"],)], 'vt' : [(N_("Virtualization"), ["virtualization"])], 'cluster' : [(N_("Clustering"), ["clustering"])], 'clusterstorage': [(N_("Storage Clustering"), ["cluster-storage"])] }" It has gotten to the point in which the script is looking for the image #1 and does not find it. The problem is that when anaconda exits the Logical Volume "/dev/mapper/VolGroup-LogVol03" that I'm using for the installation gets corrupted in such a way that I cannot run anaconda again using the same device. Moreover the "mount" has problems managing this device. After anaconda exits the "mount" command gives no hint of /dev/mapper/VolGroup-LogVol03, when I try to mount it the it say that it is already mounted or busy. In any case, I cannot mount it or un-mount it. These leaves me with the rebooting option. Which is very time consuming and would prefer other possibilities. Any comments??? Regards Joel

Loading network modules
by Daniel F. de Araujo 12 Jan '07

12 Jan '07

Hello List, It is my understanding that the mk-images script creates initrd, which contains the list of modules that need to be loaded before anaconda runs. If I want to make sure a new network module is loaded before anaconda starts, do I simply need to modify the NETMODULES line in mk-images.ppc, modify the module-info file, and then rebuild? BTW, this is for RHEL4u5. Thanks in advance for the help. Regards, -Dan -- Daniel F. de Araujo IBM Linux Technology Center

Need help wth kickstart setup of network devices. ifcfg files being renamed to .bak
by Howard Wilkinson 12 Jan '07

12 Jan '07

Can anybody point me to the code that is renaming the ifcfg-<device> files I am creating in the post install part of kickstart. They end up as ifcfg<device>.bak and get replaced by DHCP entries. As we run our servers with bonded interfaces I need to get these device to come up as slaves to the bond device which has a static address. I know this happens after the %post section has run and I am fairly sure it happens after the reboot and once the rc.sysinit hhas run for the first time. I do not have firstboot installed or any of the system-config-* packages so I have eliminated them from the path. I am fairly sure it is not anaconda itself that is doing this, but cannot for the life of me see where it could be happening. I am running a slightly extended FC6 install with minimal packages.

buildinstall puts minstg2.img and stage2.img to images but anaconda looks for them in Fedora/base
by Marius P. 10 Jan '07

10 Jan '07

Just installed FC6 and tried to build a new respin with latest updates. Apparently, minst2.img and stage2.img are now in images in FC6. While building new respin buildinstall put both .img files to images directory however during installation anaconda were still looking for them in Fedora/base. Is this a known issue? It was enough to move both .img to the Fedoara/base in the tree and installation when smooth. /M.

Have to wipe LVM after repeated reinstall
by Christopher Boumenot 09 Jan '07

09 Jan '07

Greetings, I have been noticing a problem with anaconda when repeatedly installing a server with a disk configuration involving LVM. Anaconda will fail because it cannot create the volume group VolumeGroup00. After looking at the disk, it is clear why - the volume group still exists. To get around this I wrote a simple %pre script that destroys all PGs, VGs, and LVs it knows about. A copy of that script may be found at the bottom of this email. Is this the correct solution, or should Anaconda be handling this? I have verified this behavior on RHEL 4u2, and CentOS 4u4. ---> kickstart.cfg <---- install text url --url http://192.168.1.88/centos/4.4-i386 skipx mouse none #reboot authconfig --enablemd5 --enableshadow lang en_US.UTF-8 langsupport --default en_USs.UTF-8 en_US.UTF-8 keyboard us firewall --disabled selinux --disabled bootloader --location=mbr timezone --utc US/Eastern network --device eth0 --bootproto dhcp clearpart --all --initlabel partition pv.00 --size 1 --grow volgroup VolumeGroup00 pv.00 logvol / --vgname VolumeGroup00 --size 4000 --name=root.fs logvol swap --vgname VolumeGroup00 --size 2048 --name=swap.fs logvol /var --vgname VolumeGroup00 --size 8192 --name=var.fs logvol /usr --vgname VolumeGroup00 --size 4096 --name=usr.fs logvol /opt --vgname VolumeGroup00 --size 16384 --name=opt.fs %packages --resolvedeps @Web Server # Destroy anything related to LVM %pre --interpreter /usr/bin/python import os, re, sys lvm = "/usr/sbin/lvm.static" fouth = open("/tmp/lvm_wipe.log", 'w') print >>fouth, "Starting LVM wipe ..." if not os.path.exists(lvm): print >>fouth, "Error: cannot find %s" % lvm sys.exit(1) for lv in (os.popen("%s lvscan" % lvm).readlines()): m = re.match(r".*'([^']+)'", lv) if m: cmd = "%s lvremove %s" % (lvm, m.group(1)) print >>fouth, cmd print >>fouth, os.popen(cmd).read() for vg in (os.popen("%s vgscan" % lvm).readlines()): m = re.match(r'\s*Found volume group "([^"]+)"', vg) if m: cmd = "%s vgremove %s" % (lvm, m.group(1)) print >>fouth, cmd print >>fouth, os.popen(cmd).read() for pv in (os.popen("%s pvscan" % lvm).readlines()): m = re.match(r'\s+PV (\S+)', pv) if m: cmd = "%s pvremove %s" % (lvm, m.group(1)) print >>fouth, cmd print >>fouth, os.popen(cmd).read() fouth.close() Thanks, Christopher

fc6 problem with ks.cfg from http on nonstandard port?
by Jane Dogalt 09 Jan '07

09 Jan '07

Any ideas/suggestions? This may be a fc5->fc6 regression as I think I didn't change anything moving to fc6. I looked over code until I couldn't figure out where mygethostbyname() was defined, to verify that it is paying attention to the :<portnum> syntax. Maybe theres already a closed bug that my simplest of bugzilla searches failed to find? -dmc/jdog 05:33:50 INFO : file location http://10.0.2.2:11252/os.cfg 05:33:51 INFO : transferring http://10.0.2.2:11252//os.cfg to a fd ^[ 05:34:27 ERROR : cannot determine address family of 10.0.2.2:11252 05:34:27 ERROR : failed to retrieve http://10.0.2.2:11252///os.cfg __________________________________________________ Do You Yahoo!?
