When one preupgrades to F16 do the old 500+ user ids get converted to
1000+, or is it expected the user will do this manually? In any case I
would be interested in knowing how to do this manually.

No need for a (not that complex) find command, see the chown option:
--from=CURRENT_OWNER:CURRENT_GROUP, in conjunction with -R and -L this
makes life fairly easy. Genuinely removeable shares (i.e. those you
might take between computers) have issues with UIDs anyway and are
probably running something without it (e.g. NTFS), semi-removable
shares (e.g. USB drives that are always connected to your machine)
just need to be mounted when you do this.
You would still need to do it for all groups and users that you were
updating, I agree you really don't want to update an existing system
unless you have to (to make it play well with Ubuntu for instance).

Configuring new ethernet interfaces
by Alex
Hi,
I have an existing fedora15 x86_64 server with two interfaces that
I've moved to a different motherboard and processor with dual onboard
Intel 1000mbs ethernet controllers on it (e1000e driver). After moving
the system to the new motherboard, for some reason the ethernet
interfaces changed from eth0 and eth1 to eth4 and eth5.
Why did this happen, and how do I change it back to eth0 and eth1?
It looks like udev has something to do with this?
Thanks,
Alex

unwanted logout in xfce
by Stuart McGraw
I am a refugee from Fedora 15's Gnome-3 that has found
refuge in Xfce. I'm am only sad that Gnome-3 didn't come
out sooner so I could find Xfce sooner -- it meets my needs
and expectations very well.
However, I am having one issue since I changed... I leave
my machine on and running overnight (have a bittorrent
client running) but the next morning I find I am logged
out. This happened again last night. According the logs
there was no reboot. 'last' is hard to interpret but I
*think* it shows I left the machine around 22:56 last
night and was logged out at 23:33.
I have not been able to find any setting that might be
responsible for this. Any suggestions about where to look?
(This is a desktop machine and power management is set
to "none" on external power. Screensaver is set for 30 min
but not set to logout or even lock screen and test this
morning indicates it is not culprit.)

Fedora 16 beta vice Knoppix
by JB
Hi,
I performed a simple home test, a comparison of startup and shutdown times of:
- Live-CD Fedora 16 beta - systemd parallel boot, GNOME 3
- Live-CD Knoppix 6.7.1 - microknoppix-fast-parallel-boot (based on SysV/LSB
scripts), LXDE;
note that Knoppix does decompression while executing
The times measured were:
t1 - time between machine turned ON and showing of live system DE menu
t2 - time between machine "Shutdown" from DE menu and actual machine shutdown
Note: no custom configuration or other user activities were performed.
Notebook 1:
-----------
Lenovo TP R61i, Intel Pentium Core 2 Duo 1.86 GHZ, Intel Mobile 965GM,
2 GB RAM, HD, CD-RW, sound, internal ethernet and wireless.
F16 beta
average t1=3m8s
average t2=10s
Knoppix
average t1=1m37s
average t2=20s
Notebook 2:
-----------
HP Nx6110, Intel Celeron M 1.3 GHZ, Intel Mobile 915GM, 768 MB RAM, HD, CD-RW,
sound, internal ethernet.
F16 beta
average t1=3m42s
average t2=26s
Knoppix
average t1=2m38s
average t2=20s
Results interpretation.
-----------------------
Knoppix won by a wide margin, while:
- Knoppix having microknoppix fast-parallel boot (based on SysV/LSB scripts)
and DE with low resources usage and tailored for desktops
- Fedora having systemd parallel boot and DE tailored for small and simple
devices

FC15 Upgrade Gnome Issue Dell Inspiron
by Tod Thomas
I burned the DVD version of the distro so I could update an old dell
Inspiron 600M laptop from FC13. It seemed to go well until I rebooted
then a message flashed by saying something about Gnome3 and
comparability with older displays. I get a Gnome desktop but its not
working quite right. I'm getting ready to look at it again after taking
a break but I just wanted to ping the list to see if there is maybe
something obvious I can do or if my problem is familiar to anyone.
TIA - Tod

Blank SELinux alerts
by Joe Zeff
For the last six years, I've been running BOINC on my computer and
participating in various WCG projects starting with Folding@Home as well
as Einstein@Home. Recently, a badly-written project started spewing
SELinux alerts because it was trying to walk various directories in
/proc where it has no business being. (BOINC runs in permissive mode; I
get the alerts, but the actions are allowed.) The only way to stop this
was to abort the unit and, eventually, unselect the project completely.
Just before I did that, I accidentally opened the troubleshooter twice.
Before I could deal with the first instance, it closed and a second
window opened, blank. Since then, I've been getting several alerts a
day, but whenever I click on the icon, there are no alerts showing.
I've reported this to fedoraforum.org, but so far, no response. Does
anybody here know what file/files sealert is looking at that might be
corrupted?

Compiz download problems ?

I am getting the following warnings when I try to update.
ERROR with rpm_check_debug vs depsolve:
compiz-fusion-extras = 0.8.6 is needed by
compiz-fusion-extras-gnome-0.8.6-1.fc14.x86_64
Please report this error at http://yum.baseurl.org/report

I have stopped all compiz, emerald and ccsm updates and the rest of my
updates upload without problems.
Is anybody else having this problem or should I file a bug?
