----------------------------------------
Hello, I'm a Gentoo Linux developer and I found this bug due to the way the
init script for puppet is implemented in our distribution's package.
First of all, please correct me if I'm wrong in the assumption that this is the
correct behaviour for a system-level puppet master: the master process is
started by root; it drops privileges to the puppet user, and then keeps
running; the libdir used is /var/lib/puppet. If the process is started by
non-root, a non-system instance is running, and the libdir is ~/.puppet.
This being the case, when the SIGHUP signal is sent to a system instance
(running as puppet), it tries to re-start the master process as a non-root
user, causing it to look into ~/.puppet instead of /var/lib/puppet.
Furthermore, since the environment is not cleared before dropping privileges,
ENV['HOME'] is still set to "/root", causing it to look for /root/.puppet (and
thus failing).
Unless we're doing something very wrong in Gentoo, the SIGHUP handling is
unreliable for system instances (which tend to be the ones where you want to
use SIGHUP).
