Package: icinga-common
Version: 1.7.1-4
Severity: serious
Tags: patch
icinga-common's postinst has the following construct:
| cp -a -f "$conffile" "$conffile".tmp
| sed -e ... < "$conffile" > "$conffile.tmp"
In my case, $conffile is a symlink:
} lrwxrwxrwx 1 root root 26 Nov 1 15:11 /etc/icinga/icinga.cfg ->
from-git/static/icinga.cfg
so the postinst does effectively sed < $file > $file, and we all know
that this doesn't work and results in $file being empty at the end.
I propose to use sed's -i instead:
