Package: mrtg
Version: 2.17.10-5+deb12u2
Severity: important
Installing MRRTG with SysV-rc yields:
Selecting previously unselected package mrtg.

Then, the installation process hangs.

Killing debconf fronted leaves package in iF state. Mrtg is started and runs in
background, though.
Looking into where the hang occurs:
~ # bash -x /var/lib/dpkg/info/mrtg.postinst configure
+ set -e
+ getent group
+ grep -q mrtg
+ getent passwd
+ grep -q mrtg
+ chmod 2750 /etc/mrtg
+ chmod 0640 /etc/mrtg/mrtg.cfg
+ chown mrtg:mrtg /etc/mrtg

=> And hangs here.
Adding an "exit 0" in line 56 (before the dh_installinit/13.11.4 block) allow
the package configuration to succeed and the package state set to ii. Adding
exit 0 later in the script does not solve the hang, I have no explanation for
that.
