OT:Question on NVME disk direct access?
by Michael D. Setzer II
I'm the maintainer of the G4L disk imaging project since 2004, and I use
Fedora as the build platform. Currently using Fedora 27.
Have an issue from a user that has me baffled, so am hoping someone here
might provide some guidance.
The program boots a linux kernel, and basically uses dd to copy the
disk/partitions thru a compression program and creates an image file on ftp
server or local device.
I don't have any physical nvme disks, but using virtualbox I created a 4M
disk, and 2 - 2M partitions within it. In testing that, the 4M disk compresses to
a 30K file, and the 2M partitions compress to about 15K each. That is what is
expected with cleared partitions.
The user though, with a real 256G disk doesn't seem to get any compression
of the disk or partitions. Them resulting images are close to the same size as
the disks or partitions??
He can mount the partitions and see the files, so there must be something
going on that I don't see?
Would think that accessing the /dev/nvme0n1 or partitions /dev/nvme0n1p1
thru p5 would act the same as accessing /dev/sda or /dev/sdax partitions.
The images that are created pass the compression program test, so it is
reading data, but in some form that doesn't compress much, and user has
used a program to clear the unused space?
Thanks for your time, and any ideals.

upgrade to 28 beta question?
by ToddAndMargo
Hi All,
This worked under 27. Anything different under 28?
Many thanks,
-T
FC 27 -->> FC 28:
# rpm --rebuilddb
# rpm -Va --nofiles --nodigest
if anything is too new, do a
# dnf downgrade offender(s)
# dnf --enablerepo=* update --refresh
# dnf install python3-dnf-plugin-system-upgrade
# dnf system-upgrade download --refresh --releasever=28 --allowerasing
# dnf clean packages <-- optional
# dnf system-upgrade reboot

Lost touchpad vertical scrolling after upgrading this laptop from
F25->F26
by Kevin Cummings
Hi Folks,
I just recently upgraded the F25 on this laptop (Dell Inspiron 1520) to
F26. It mostly went well, except that I seem to have lost the ability
to use the vertical scrolling part of my touchpad. I'm running the MATE
desktop, so the first thing I did was to check the mouse configuration
in System->Preferences->Mouse. In the touchpad tab, I see that Vertical
Edge Scrolling is indeed checked, and un-checking it and re-checking it
does not bring the functionality back. I can use two-fingered vertical
scrolling (it also is checked), but I am not an expert, and it seems to
have the side effect of backing up if I move my second finger down into
the horizontal scroll area of the touchpad when trying to do a large
vertical scroll.
A secondary problem to this is that if I move the mouse pointer into
the right side scroll bar, then click to grab it and move the pointer
vertically, it does scroll the window, but the pointer moves faster than
the scroll bar, and to go all the way (either way) often takes multiple
attempts.
Finally, if I place the mouse below (or above) the scroll bar, it does
not scroll by just one page, very often I put the pointer closer to the
top or bottom of the scroll bar area, and it scrolls all the way to the
top or bottom. For this one, how can I get the old behavior back?

what package would one bugzilla package group issues against?
by Robert P. J. Day
seems to me that some of the current dnf packages related to
virtualization and containers could be adjusted and cleaned up, but
i'm not sure against which component one would file a BZ issue
against.
first, the Virtualization group:
$ dnf group info virtualization
Last metadata expiration check: 0:18:41 ago on Fri 06 Apr 2018
05:18:28 AM EDT.
Group: Virtualization
Description: These packages provide a graphical virtualization
environment.
Mandatory Packages:
virt-install
Default Packages:
libvirt-daemon-config-network
libvirt-daemon-kvm
qemu-kvm
virt-manager
virt-viewer
Optional Packages:
guestfs-browser
libguestfs-tools
libvirt-client
python-libguestfs
virt-top
$
i'm still perusing that group to convince myself that its contents
really reflects what is required for "virtualization" on fedora --
it's possible that there are newer packages that should be included,
but i'm still poring over it.
next, the "container-management" package seems awfully
docker-centric:
$ dnf group info container-management
Last metadata expiration check: 0:21:50 ago on Fri 06 Apr 2018
05:18:28 AM EDT.
Group: Container Management
Description: Tools for managing Linux containers
Mandatory Packages:
cockpit-docker
docker
Optional Packages:
docker-registry
fedora-dockerfiles
$
more to the point, these days, it should incorporate the "docker-ce"
package, not "docker", yes? (and i vaguely recall from somewhere that
the fedora-dockerfiles package was not terribly up to date.) anyway,
given container technologies other than docker, it seems that that
group name is a bit misleading.
and if one can have a package group devoted to docker, one imagines
it would be appropriate to have one dedicated to, say, kubernetes as
well, but there isn't one.
anyway, it just seems like there could be a refactoring of a number
of package groups to make them more consistent and current. thoughts?

can i define my own dnf package groups?
by Robert P. J. Day
related to my earlier query (and i'll have a couple more about
package groups and virtualization before i'm done), is there any way
to define my own package groups for personal use, other than manually
hacking the groups.xml file?
i've scanned the dnf man page, and i don't see any indication that
that's possible -- perhaps a dnf plugin somewhere i haven't found?

using "dnf group remove" to *totally* remove all virtualization?
by Robert P. J. Day
a couple more dnf/virtualization questions and that should be it.
first, is there any option, when removing a package group with "dnf
group remove", to remove even those packages that were installed
manually? last time i looked (and i believe i just reconfirmed that),
dnf keeps track of which packages were installed manually so that,
when you remove a package group, it will *not* remove packages that
had been installed manually. i'm not aware of any way around that, but
perhaps i missed something in the man page. or maybe there's a dnf
plugin?
finally, the reason i'm asking about this is that i'm writing a
tutorial on how to get started with virtualization on fedora, and i
wanted to start from the perspective of a system that had absolutely
no virtualization support on it whatever, and show what one could do
as one added one virtualization component at a time; hence, my attempt
at trying to remove the entire Virtualization package group (even
though i don't think that would come close to getting rid of all
virtualization).
by the way, that last paragraph inspires the question -- does a
regular fedora system *require* even the smallest aspect of
virtualization to run properly? as in, if i had no need for
virtualization support, is it feasible to remove every single
virt-related package from the machine and not break something?

html to man page
by JD
Hi all,
I have an app that has no manpage, but has about 170 html files,
all of which index into a subset of the 168 files.
I would like to use an app that will produce a single manpage like
text file.
Is there an app that can do this?
I saw a few apps on google search, but none of them are producing what I
want.
Thanx.

Help understanding the kernel release schedule
by Flo H
Hi,
I am confused about the way the kernel packages land in Fedora, specifically Rawhide, and was wondering if someone could shed some light on this issue.
Looking at [1], I see that the kernel in the updates repo is 4.17.rc. How is that possible? What is the source for 4.17? A build of linux-next?
(Looking at [2] we see that 4.16 has just been released this week.) So what is 4.17.rc?
Please let me know if I am asking on the wrong mailing list. Should I rather bother the packagers in the kernel list?
Thanks!
