I'm sure you already know this, but wildly / randomly deleting
things in
/tmp is a bad idea...
Well, here's the story. It was a Debian box, and somehow, mountnfs.sh
wound up at S99 in /etc/rc2.d. I'm not sure how that happened, but it
raises some potential questions:
Converting this to a PostgreSQL on Debian question: is it a good
admin practice to go ahead and set TMPTIME=-1 in /etc/default/rcS on
Debian servers running postgres?
If the answer is "yes", then it becomes a more purely Debian
question: what are the ramifications of not cleaning out /tmp at boot
using initscripts?
More widely: are there other non-Debian-based distributions that have
a similar facility for wiping /tmp at boot? Is changing the timing
easy? Is the disabling mechanism the same?
Maybe not having seen too many prior instances of this particular
issue is a good sign that no one is obliterating the contents of /tmp
after postgres has started, but the fact that Debian has tools in
initscripts that seek to clean out /tmp this makes me think a mention
of this in the PostgreSQL documentation might be a good idea (perhaps
in 14.6: Post-Installation Setup?).
But I'd be curious to know the perspective of other Debian/PostgreSQL
admins on where they think the issue really lies or even whether
there is a perceived issue.
