Bug Description

On a current debian host (testing/unstable) debian defaults to per-user temp dirs. Mine are, for instance:

TMPDIR=/tmp/user/1000
TEMP=/tmp/user/1000
TEMPDIR=/tmp/user/1000
TMP=/tmp/user/1000

When doing the early things, such as "apt-get remove grub" - mkinitramfs gets called in the chroot, and this fails because the tempdir vars are leaking through - turns out, /tmp/user/0 (root's tempdir) doesn't exist in the guest.

In any case, dib should block the passthrough of TMP* env vars.

This is only a problem when limpam-tmpdir module is enabled, not something very common. Testing a possible solution.

    Force empty $TMPDIR inside the chroot

    There are some situations (use of libpam-tmpdir) where the $TMPDIR is
    defined per user, so any sudo call will define an specific $TMPDIR for
    the root user which doesn't exist inside the chroot.
