Package: util-linux
Version: 2.20.1-5.3
Severity: important
Tags: patch
Usertags: usrinitramfs etcinitramfs
The attached patch is to apply for jessie, so isn't appropriate
to use until after wheezy is released. See
http://wiki.debian.org/ReleaseGoals/MountUsrInInitramfs
for further information.
To summarise, the intent is to mount /usr (and potentially also
/etc for certain specialised use cases) in the initramfs, so that
/usr is available as soon as init starts.
The fsck -R option ignores filesystems which are mounted when
checkfs runs. Currently this is only the rootfs (plus special
filesystems which aren't checked). With /usr (and /etc) mounted
early, the -R option therefore needs extending to support these
filesystems as well so that we check them manually in checkroot,
and skip them in checkfs.
The upload of this change will need coordinating with the
initramfs-tools and sysvinit packages so that we get the
dependencies correct so that usr is checked (and only checked
once, not zero or twice).
Thanks,
Roger
