Proposed text:

Changes to the configuration and defaults of tmpfs filesystems

In previous releases, tmpfs filesystems were mounted on /lib/init/rw,
/dev/shm and optionally on /var/lock and /var/run.  /lib/init/rw has
been removed, and the others have been moved under /run.  /var/run and
/var/lock were configured using RAMRUN and RAMLOCK in
/etc/default/rcS.  All tmpfs filesystems are now configurable using
/etc/default/tmpfs; the old settings are not migrated automatically.

                            Old setting       New setting
Old location  New location  /etc/default/rcS  /etc/default/tmpfs
/lib/init/rw  /run          N/A               N/A
/var/run      /run          RAMRUN            N/A
/var/lock     /run/lock     RAMLOCK           RAMLOCK
/dev/shm      /run/shm      N/A               RAMSHM
N/A           /tmp          N/A               RAMTMP

The migration of data to the new locations will occur automatically
during the upgrade and will continue to be available at the old and
new locations, with the exception of /lib/init/rw.  No action is
required on your part, though you may wish to customise which tmpfs
filesystems are mounted, and their size limits, in /etc/default/tmpfs
after the upgrade is complete.  Please see the tmpfs(5) manual page
for further details.

If you have written any custom scripts which make use of /lib/init/rw,
these must be updated to use /run instead.

/tmp is now a tmpfs by default.  While this should not affect your use
of the system in any noticeable way, please note that
- the contents of /tmp are not preserved across reboots;
- /var/tmp exists for this purpose
- the maximum size of /tmp may (depending upon your specific system)
  be smaller than before.  If you find that there is insufficient
  free space, it is possible to increase the size limits; see
  tmpfs(5).
- applications which create excessively large files in /tmp may cause
  /tmp to run out of free space.  Such applications should not be
  using /tmp, and require fixing.  Please consider filing a bug report
  against the application in question if you experience such an
  occurrence.

I've committed Charles's last patch (minus the contentious sentences) as
r9767; thanks.
