Package: systemd
Version: 241-5
Severity: normal
Tags: patch
Dear Maintainer,
After upgrading to Debian 10 we noticed a slightly different behaviour
in /lib/lsb/init-functions.d/40-systemd which caused one of our scripts
to break and which also causes some /etc/init.d files like /etc/init.d/mysql
to no longer to display their help text when calling them without a parameter.
The root cause are accesses to the $1 and $2 variables without checking
if they are defined beforehand. When running code using "set -u", this
causes the above mentioned error.
I've outlined this very simple fix which bypasses all further tests if
$1 and so on are undefined.
$ diff -C 9 40-systemd.orig 40-systemd
