/tmp in RAM has been extremely common on Solaris for more than 10 years
(/tmp in RAM is the default there). I recall every SuperSPARC and
UltraSPARC box at Uni had this configuration.
IMO, it is a very clearly cut case: applications cannot reasonably make any
assumption about /tmp for any non-trivial usage, and they are to use $TMPDIR
to locate the system tmp directory in the first place if they want to use
it.
This is NOT a Debian thing. It is not even a new requirement, it is so old
that TMPDIR has already made it into POSIX/SuS...
