/dev/live no longer being created since udev-153 update?

[Aaron Cohen]

Hi all,

  If I "rdbreak" on the kernel command line, I see that /dev/live is
created correctly (though it now points to
/dev/disk/by-uuid/<aBunchOfDigits> where formerly it pointed to
/dev/disk/by-label/DiskLabel).

  After switch_root though, /dev/live is gone.

  If I add "udevlog" to the command line, I see the following in
/dev/.udev/udev.log (see particularly where it says, "link_update: no
reference left, remove '/dev/live'").  I'm not positive it's the
udev
update that is causing my problem, but it's my current best guess.

Aaron,

I am experiencing the same issue and tracked it down to the udev
update just not exactly why.   I reset the overlay and only installed
udev and had the issue on the next boot.

Thanks!
Darren

Ah! Thanks for the warning. I noticed last night that /home wasn't
mounting any more, and assumed it was something naughty I'd done. I was
going to waste a few hours this morning troubleshooting it, so I'm glad
I don't have to.

I discovered a while back, working around a synaptics bug, that you can
specify a version of a package in the kickstart file. So rather than

	synaptics

I was specifying

	synaptics-1.0

and making sure the old rpm was available in a local repo. My suggested
workaround here is to specify an older version of udev, and make it
available. Two possibilities: either specify the one in the release
repo, or download the one before the problem occurred and put it in a
local repo. The former is easier, but it might break some dependencies.

[James Heather]

Hmm. I can't get it to work by specifying udev-151-9 in the kickstart
file. I don't know why.

However, I can confirm that you can boot up off your USB stick, log in
to a vt as root, and

    yum downgrade udev

and then reboot, and it'll mount home. (You might also need to

    rm -rf /home/*

if it's created some home directories by that point, but please do check
it hasn't mounted your persistent home first...)

This could also be done with a %post in the kickstart file.

Here are excerpts from an IRC chat I had yesterday (please do not
assume I understand all of it..)


<haraldh> [udev] 153.3 does not delete the database
<haraldh> thus it knows the old symlinks
<haraldh> and cleans them up
<haraldh> because cdrom_id fails on /dev/sr0
<haraldh> because it's busy
<haraldh> because cdrom_id does not see it mounted
<haraldh> because it's not mounted inside the new root


And I think that the recommended fix is to upgrade dracut as well:

haraldh> # ls -l  /dev/.initramfs/live
<skew321> haraldh: there is nothing there!?
<haraldh> does the directory exist?
<skew321> no
<haraldh> if not you have an old dracut version
<skew321> fedora 13
<haraldh> without the patches I told you
<haraldh>  commit 91bb250aedfbdac23b760940cd7459327c2be349
<haraldh>  commit 847b618b4c8d13c474e7e282cc4c40913bae7aab
<haraldh> ..
<haraldh> try the f14 version, should work on f13


<haraldh> the fix is to mount it also in /dev/.initramfs/live
<haraldh> so it can be seen in /proc/self/mountinfo


If anyone can understand and summarize this in non-IRC language I
guess a number of people would be grateful, including myself of
course.
