Subject: Upgrade to 0.100-1 removes links from /etc/rcS.d; udev doesn't start

Date: Thu, 07 Sep 2006 23:57:42 -0400

Package: udev
Version: 0.100-1
Severity: critical
Justification: breaks the whole system

After upgrading udev from 0.098-2 to 0.100-1, I found that udev no
longer started automatically at boot time, because the
/etc/rcS.d/S03udev and /etc/rcS.d/S36udev-mtab symlinks were no longer
present.  This pretty much hoses the system, since various important
drivers don't get loaded; neither GDM or even the gettys came up, and I
had to boot in single-user mode.

Purging (with dpkg --purge --force-depends) and reinstalling the udev
package resolved the situation.  Probably just running update-rc.d
manually could have resolved it too.

Hi,

apt-get install --reinstall does the trick, too.

I can't see how the package could do this. Do you?
Why do you believe that udev removed the links?

Subject: udev: reproducible with 0.098-2

Date: Fri, 08 Sep 2006 10:14:21 +0200

[Message part 1 (text/plain, inline)]

Package: udev
Followup-For: Bug #386500

This problem has hit me as well, but upgrading to 0.098-2.

However, I lost not only the udev symlink but also ntpdate. I suspect a
race somewhere in the installation order corellating with sysv-rc or
sysvinit or initscripts which have been installed in the same run.

I am attaching the dpkg.log, that I all I can provide now.

Eduard.

Hi,

After the last upgrade of udev a lot of services did not start due to
missing device files. Downgrading udev fixed my system again. 

I see the same upgrading behaviour as Mike Paul saw:

arjan@nebula:~$ ls /etc/rcS.d/*udev*

So upgrading udev indeed triggers this bug,

I can confirm this. No start links for udev after upgrade. Please change
severity to critical! These are the packages that I upgraded together
with udev:

linux-kernel-headers
udev
console-common
fetchmail
kernel-package
libgphoto2
libselinux
libsepol
shared-mime-info
sysvinit
wireshark

Hi,

I found the problem. The postinst script calls update-rc.d which should
be fine, bu update-rc.d is broken.

Content postinst:
# Automatically added by dh_installinit
if [ -x "/etc/init.d/udev" ]; then
        update-rc.d udev start 03 S . >/dev/null || exit $?
fi
# End automatically added section
# Automatically added by dh_installinit
if [ -x "/etc/init.d/udev-mtab" ]; then
        update-rc.d udev-mtab start 36 S . >/dev/null || exit $?
fi
# End automatically added section

Manual try:

ls /etc/rcS.d/*udev*
/etc/rcS.d/S03udev  /etc/rcS.d/S36udev-mtab
arjan@nebula:~$ sudo update-rc.d udev start 03 S .
   /etc/rcS.d/S03udev
 System startup links for /etc/init.d/udev already exist.
arjan@nebula:~$ ls /etc/rcS.d/*udev*
/etc/rcS.d/S36udev-mtab
arjan@nebula:~$ sudo update-rc.d udev start 03 S .
 Adding system startup for /etc/init.d/udev ...
   /etc/rcS.d/S03udev -> ../init.d/udev
arjan@nebula:~$ ls /etc/rcS.d/*udev*
/etc/rcS.d/S03udev  /etc/rcS.d/S36udev-mtab

So when the links already exists update-rc.d devices to remove them.
Uughh.

I have cloned the bug report and reassigned to sysv-rc with severity
critical as it breaks other programs.

Hi,

I found the problem in update-rc.d. There is a little logic error in one
of the functions update-rc.d. After i fixed that it worked again:

arjan@nebula:~$ ls /etc/rcS.d/*udev*
/etc/rcS.d/S03udev  /etc/rcS.d/S36udev-mtab
arjan@nebula:~$ sudo update-rc.d udev start 03 S .
 System startup links for /etc/init.d/udev already exist.
arjan@nebula:~$ ls /etc/rcS.d/*udev*

Ah, then it was introduced in version 2.86.ds1-16.  Thank you for the
patch.  I've included it in svn instead of my proposed patch.
