Hi Joachim,

We used to have "exec" scripts in addition to "setup" scripts, which
were run once per command being run, rather than once per session.
These lived in /etc/schroot/exec.d rather than /etc/schroot/setup.d.
These were never used for any practical purpose, so they were removed
some years back.  However, we could certainly add them back to make
this possible.

Should anything else be updated as well?  While it's possible to
update NSS databases etc., these can be potentially expensive
operations, while copy resolv.conf is not.


Regards,
Roger
