Package: sysvinit
Version: 2.84-3
Severity: wishlist
Tags: patch
Hi,
after the big flamewar about writing to /etc on debian-devel again I
finaly implemented the suggestion of a /run and packaged it all up.
The patch changes nothing for the current setup but opens the way for
the admin to create a /run and move/links files there.
README.read-only-root describes the steps to take and what remains to
be addressed.
Once this is included other packages can start moving their files to a
more fitting place if so configured. As it is a base system with a RO
/ will give out some errors (see readme file) but they can be savely
ignored since they don't affect a correctly setup system.

+Things to do to use a read-only / filesystem:
+
+- Some filesystem must be writeable. The prefered mountpoint is
+ /run. The mountpoint you decide to use must be configured in
+ /etc/volatile.conf. If you go for a ramdsik you need to create a
+ filesystem on it before checkroot.sh. If /run is no virtual
+ filesystem (deduced by being on /dev/*, ramdisk is a virtual device
+ but not a virtual filesystem) its fs_passno (the sixth field in the
+ /etc/fstab file) must be 0. It will allways be checked after root is
+ checked regardless of the number and may not be checked again by
+ checkall.sh (issuing a fsck -A). If you don't want it to be checked
+ at all hack checkroot.sh.
+
+ The easiest thing here is a simple tmpfs.
+
+- /dev needs to be writable, devfs does the job fine but you need to
+ adjust your inittab and fstab. If you use a ramdisk you have to
+ create and mount it yourself. If you create its own filesystem you
+ have to fsck and mount it yourself. In both cases you also need a
+ mini /dev on / containing the device node for the real /dev. Using
+ /run/dev as dev is the next best thing to devfs. (see volatile-skel)
+
+ The easiest thing here is devfs.
+
+- /etc/volatile-skel can contain any dirs/links/files that have to be
+ present on /run. If you don't want to use devfs you can place your
+ dev tree there and it will be copied to /run/dev with each boot.
+
+- create a link from /run/mtab to /proc/mounts on the real /, not on
+ /run. Create a mini /run/dev now too if you want to use it. Only
+ then mount the real /run.
+
+- link /etc/mtab to /run/mtab (you might want to move it there first)
+
+- link /etc/network/ifstate to /run/ifstate (move it first too)

Changes:
sysvinit (2.88dsf-13.3) experimental; urgency=low
.
[ Roger Leigh ]
* Non-maintainer upload.
* Support for new top-level directory /run to replace /var/run,
/var/lock, /dev/shm and /lib/init/rw as a place to store transient
writable data which should not be preserved across a system
reboot (Closes: #186892, #616571, #620191). /run fixes existing
issues with RAMRUN and RAMLOCK options using tmpfs on /var/run and
/var/lock (Closes: #423405, #481546, #564635, #607136, #620735).
Additionally, /run/shm replaces /dev/shm and may share the same
tmpfs as /run if RAMSHM is set to "no" in /etc/default/rcS. /tmp
may also be configured to be a tmpfs if RAMTMP is set to "yes" in
/etc/default/rcS. /tmp may also be configured to use /run directly if
it is symlinked to /run/tmp, for example.
Summary:
/var/run → /run
/var/lock → /run/lock
/dev/shm → /run/shm
/lib/init/rw → /run (not transitioned automatically)
/dev/.* → /run (not transitioned automatically)
These changes do not take effect until the system is rebooted as
is currently done for /lib/init/rw setup. Prior to a reboot, the
paths are made available via bind/nullfs/firmlink mounts, depending on
the platform. Following a reboot, the old paths will be converted to
symlinks, or bind/nullfs/firmlink mounts where symlinking is not
possible, to allow access via either the old or new paths, to permit
programs using the old paths to transition to use the new paths for
wheezy.
- debian/initscripts.postinst:
Take chroot detection logic from udev postinst (existing logic was
broken). Add detection logic for vserver environments and Hurd.
Trigger reboot to complete transition.
If the system has not yet transitioned to a tmpfs-based /run, set up
bind mounts as follows:
/var/run → /run
/var/lock → /run/lock
/dev/shm → /run/shm
On reboot, the system will complete the migration to a tmpfs-based
/run; this creates the directory heierachy from the old paths to
enable the use of the new /run paths prior to a restart. This means
packages may transition to using /run with a versioned dependency
upon initscripts.
Remove special handling for RAMRUN and RAMLOCK, which is now taken
care of by /run.
If in a chroot environment, just create symlinks from the new names
to the existing locations, since otherwise the changes would be
lost, and since rcS scripts aren't run the transition won't
complete.
- debian/src/initscripts/Makefile:
Provide top-level /run.
- debian/src/initscripts/doc/README.Debian:
Document new use of RUN_SIZE and LOCK_SIZE.
Document use of /run rather than /lib/init/rw.
Document use of SHM_SIZE and TMP_SIZE.
- debian/src/initscripts/etc/init.d/checkroot.sh:
Use /run in place of /lib/init/rw.
- debian/src/initscripts/etc/default/tmpfs:
Document TMPFS_SIZE, RUN_SIZE and LOCK_SIZE (Closes: #483643).
Document TMP_SIZE and SHM_SIZE.
- debian/src/initscripts/etc/init.d/mountkernfs.sh:
Create /run, /run/sendsigs.omit.d and /run/lock.
Mount /run/lock as a separate tmpfs if RAMLOCK=yes.
/run/lock has 01777 permissions to match /var/lock.
Mount /tmp as a separate tmpfs if RAMTMP=yes or / is being mounted
read-only (Closes: #503805, #585543).
Drop mounting of /var/run and /var/lock.
- debian/src/initscripts/etc/init.d/mountdevsubfs.sh:
Create /run/shm. Mount /run/shm as a separate tmpfs if RAMSHM=yes.
- debian/src/initscripts/etc/init.d/mtab.sh:
domtab mirrors behaviour of domount in mount-functions exactly, to
prevent duplicate mounts (required for bind mount support).
Bind mount /run/init and drop mounting of /var/run. Mount /run/lock
in place of /var/lock.
Mount /tmp if RAMTMP=yes.
Mount /run/shm if RAMSHM=yes.
- debian/src/initscripts/etc/init.d/sendsigs:
Use new paths:
files: /run/sendsigs.omit /lib/init/rw/sendsigs.omit
dirs: /run/sendsigs.omit.d/ /lib/init/rw/sendsigs.omit.d/
- debian/src/initscripts/etc/init.d/umountfs:
Ignore /run. Continue to ignore /lib/init/rw in order to handle
clean shutdown. No longer ignore /var/run and /var/lock.
- debian/src/initscripts/etc/init.d/umountnfs.sh:
Check for presence of .ramfs than configuration variable when
skipping /var/run and /var/lock.
Ignore /run. Continue to ignore /lib/init/rw in order to handle
clean shutdown. No longer ignore /var/run and /var/lock.
- debian/src/initscripts/lib/init/bootclean.sh
Don't clean /var/run and /var/lock (Closes: #378776). Because
these directories are now a tmpfs, cleaning no longer makes sense.
- debian/src/initscripts/lib/init/tmpfs.sh:
Read /etc/default/tmpfs and provide defaults if unset.
- debian/src/initscripts/lib/init/mount-functions.sh:
Support bind mounts in domount() (Closes: #353943).
Drop support for mounting /var/run and /var/lock as separate
tmpfs filesystems. Symlink /var/run to /run and /var/lock to
/run/lock if possible. If /var/run and /var/lock are directories,
attempt to remove and symlink if successful, or else bind mount.
- debian/src/initscripts/lib/init/vars.sh:
Read /etc/default/rcS and provide defaults if unset.
- debian/src/initscripts/man/rcS.5:
Drop documentation of RAMRUN.
Update documentation for RAMLOCK (Closes: #406685).
Document RAMTMP and RAMSHM.
- debian/src/initscripts/share/default.rcS:
Remove RAMRUN.
Add RAMSHM and RAMTMP.
RAMLOCK, RAMSHM and RAMTMP default to enabled for new installs.
.
[ Michael Biebl ]
* Remove dead usplash support code (Closes: #599241, #599734, #612594).
.
[ Martin F. Krafft ]
* Add comments to /etc/default/rcS (Closes: #530582).
.
[ Samuel Thibault ]
Hurd portability for initscripts postinst and init scripts.
Hurd does not currently support tmpfs mounts, but will do in the
future. Use firmlinks in place of bind mounts.
