Package: nethack-common
Version: 3.4.3-10
Severity: normal
By default the recover program isn't installed set-gid. The
(low-priority) configuration question about it says that it doesn't need
to be installed setgid-games on a Debian system because it's run as root
at boot time, but this isn't the case. /etc/init.d/nethack-common does
an su to the user owning the game before running recover-helper:
su --shell=/bin/sh -c /usr/lib/games/nethack/recover-helper "$owner"
Since it's running as the owner of the game it's recovering it doesn't
have permissions to create the save file and it fails.
# /etc/init.d/nethack-common start
