Currently, /lib/init/rw exists as a place for applications that need
write access early (before $local_fs) to put their data. In addition,
some abuse /dev/shm for this. A couple of years back, /run was
suggested, but /lib/init/rw ended up being chosen.
However, various upstreams are not using /lib/init/rw, they're more
likely to use hidden directories in /dev, like /dev/.udev and
/dev/.initramfs. This is both ugly and a violation of the FHS.
Various upstreams seem to now unite under the banner of /run and I
think it would make sense for us to follow suit, see  for Lennart
Poettering's mail to the Fedora devel list and  for the FHS bug
I'm therefore proposing the goal of:
- /run should exist as a tmpfs
- /var/run should be a symlink or bind mount of/to /run
- /var/lock should be a symlink/bind mount to /run/lock
- /lib/init/rw should be a symlink/bind mount to /run
- applications are free to use /run as they have previously used
/var/run. Applications using /lib/init/rw and /dev/shm are to be
changed to use /run.
/var/run and /var/lock as tmpfs is already reasonably well supported
since this has been in use in Ubuntu for a while and it's been a
supported (but optional) configuration in Debian for some time.
