[Gnu-arch-users] pfs-signature is using /tmp

[James Blackwell]

(I'm not filing a bug on this (yet?) because this one merits some
discussion.

On the mailing list tonight we had a visitor that wasn't able to use "tla
get", because his /tmp was too small. 

After probing around a bit, I traced it down to pfs-signature.c, which
uses /tmp for a couple things, one of which pertained to this particular
case. The checksum code apparently copies (via pfs) to a newly created directory
in /tmp, where it then performs its signature checks.

Doing so can cause a problem because base-0 could conceivably be quite
large, in some cases, larger than /tmp. Though the quick-apparent solution
would seem to be "Fine, then let's use . for the temp dir", this is probably
not a very friendly answer for NFS users. 

Here's some proposed solutions: 

* In this particular case, we could check (and honor) the
  TMPDIR environment flag.

Well, offhand, that's the only solution that comes to my mind. 

What do you all think?
