Package: debian-installer
Severity: important
/etc/mtab can be either a regular file updated by mount/umount, or a symlink
to /proc/mounts. Currently, it is a regular file, though the user can change
this by hand.
With linux < 2.6.26, /proc/mounts lacks information present in /etc/mtab such
as additional mount options. Thus a symlink breaks things like discquotas
which rely on parsing the additional mount options. As a result, we are
mostly all still using it as a plain file.
With linux >= 2.6.26, /proc/mounts contains all of the information in
/etc/mtab, plus more. The mount system call can now pass all of the mount
options to the kernel, so no information is missing in /proc/mounts. This
has obviously useful benefits such as read-only root, and the state in
/etc/mtab never gets out of sync with reality (there are a number of open
bugs against mount where this occurs).
Additionally, with the addition of per-process namespaces with CLONE_NEWNS to
clone(2), each process has its own set of mounts, and as such a system-wide
/etc/mtab is useless: it's only valid in one of the potentially many
namespaces and can quickly get into a horrible mess. At this point,
/etc/mtab *must* be a symlink to avoid breakage. Note that /proc/mounts is
now a symlink to /proc/self/mounts for this reason: each process has
potentially different mounts.
After discussion on #debian-devel, we came up with these points:
- we could detect the kernel version on boot, and set up a file or a symlink
as needed. However, this breaks read-only root.
- we could change on upgrades rather than boot, but because it's dependent
upon the kernel version, breakage could result if an older kernel is
booted.
- doing it at install time if a kernel >= 2.6.26 is installed is the most
robust solution.
I had a look at a number of sources (debootstrap, base-files,
debian-installer), but I have yet to find the code that initially creates
/etc/mtab (if any). Some of the init scripts will re-create it if not
present (and these could do with updating too for Lenny+1), but ideally if
d-i installs a kernel >= 2.6.26, it should just ensure that /etc/mtab is a
symlink during the install.
If we could get this change made for Lenny, that would be great.
Thanks for your time,
Roger

Changes:
sysvinit (2.88dsf-14) experimental; urgency=low
.
[ Kel Modderman ]
* Add support for s390x, thanks to Aurelien Jarno <[email protected]>.
(Closes: #641107)
.
[ Roger Leigh ]
* debian/rules:
- Add build-arch and -indep rules. (Closes: #648472)
- Remove dpatch usage.
- Use dh and debhelper compat level 9.
* debian/control:
- Add git version control information.
- Upgrade to Standards-Version 3.9.2.
- Add myself to Uploaders.
* Use dpkg 3.0 (quilt) source format. Rediffed
debian/patches/40_multiarch_libcrypt.patch which was not well
formed and failed to apply.
* initscripts:
- Make /etc/mtab a symlink to /proc/mounts. (Closes: #494001)
Note that this is only done when the root filesystem is writable
and /proc/mount is readable.
- Support the ceph network filesystem. (Closes: #580579). Thanks
to Sage Weil.
- Restore boot-time cleaning of /var/run and /var/lock, used by
systems which currently do not use a tmpfs for /run.
- Remove /lib/init/rw: Add Breaks for all packages which used
/lib/init/rw, and which now use /run. Unmount and remove
following upgrade.
- Don't create /run/.run-transition on upgrade, only on actually
setting up a transitional bind mount.
- Add Breaks on all packages previously using /lib/init/rw, in
order to permit removal of /lib/init/rw. It is not possible to
remove prior to rebooting due to initscripts being required to
be configured by the packages transitioning to /run. Remove in
wheezy+1.
- Remove trailing period from the initscripts init script log
message. (Closes: #648881). Thanks to Clint Byrum.
- /etc/network/if-up.d/mountnfs: grep: character class syntax is
[[:space:]], not [:space:]. (Closes: #631077, #645655). Thanks to
Milan Kocian and Jan-Benedict Glaw. Also simplify function logic
using a for loop rather than a while loop. Thanks to Corey Hickey.
* sysv-rc:
- Remove splash support and use of removed /dev/.initramfs.
(Closes: #643558). Thanks to Michael Biebl.
