Starting from commit 211fe3f66e6dfdaa64974931c458ab1d92afc182, if PID 1
is Shepherd 0.9.0, the bitlbee daemon was started on-demand as an inetd
service.
However, due to a logic bug, it was running as root (in a separate user
namespace though) instead of running as “bitlbee”. The bug is that we
were spawning “bitlbee -u bitlbee” as root; normally, bitlbee would
setuid to the “bitlbee” user early on, but since it was in a separate
namespace and with a minimal /etc/passwd, it couldn’t do anything and
kept the current UID (that UID was 1000 inside the user namespace, but 0
outside).
Fix coming soon…

Fixed by commit ecfcdff23a5ce390a7edc019c1f1216c4843dc04: the bitlbee
process is now started as “bitlbee” right from the start.
I reviewed other users of ‘least-authority-wrapper’ that were recently
introduced and didn’t see other mistakes of that kind. You’re welcome
to take another look to make sure!
