Package: udev
Version: 204-12
Severity: normal
Tags: patch
The udev initramfs script is executed with set -e, and attempts to clear
out the contents of /sys/kernel/uevent_helper at boot. If
CONFIG_UEVENT_HELPER is not set this file doesn't exist, setting it
fails and the boot stops. The script should check that the file exists
and is writable before trying to write to it.
A trivial patch to do that is attached.
Additionally udev.init and udev.postinst have checks for the existence
of that file which would stop udev from being started under sysvinit if
that compatibility option is not set. I'm not entirely sure what should
be done about them.
The kernel team should possibly be notified about keeping this option
enabled for the jessie release to avoid breaking partial upgrades.
