Bug#576425: pbuilder: Don't fail if TMP != /tmp (aka, don't fail with libpam-tmpdir)

[Frank Lin PIAT]

Package: pbuilder
Version: 0.196
Severity: normal

Hello,

pbuilder fails if TMPDIR is set to a subdirectory of /tmp (for instance, 
libpam-tmpdir configures per-user temporary directory, like
TMPDIR=/tmp/user/0)

This is quite trick to diagnose, because dpkg-deb log is missleading:

> dpkg-deb: failed to make tmpfile (control): No such file or directory

I guess the easiest way to solve the issue would be reset the value of
TMPDIR (and TMP to be on the safe side).

Regards,

Franklin
