Brian Ginsbach 52344913d3 Add a way to signify undetermined EOL 
Replace setting an artificaly high date and converted date for
operating systems with no EOL (rolling) or the EOL is still to
be determined. This makes it easier for humans and saves making
a comparison (when using an artifically high converted time)
will always be false (EOL=0).

An example entry

        os:AGreatOS 2.0:👎

The converted time (seconds since the epoch) could be specified as
zero but this typically means the OS is out of date (now), A value
of -1 is a convention indicating no EOL.

Harden mount options for /var, check also /dev and /run 
There should not be any need for char/block devices in /var, so
propose nodev. Sockets are not affected.

Check also /dev for noexec,nosuid and /run for
nodev,nosuid. Historically there was /dev/MAKEDEV script but that's
long gone.

In case a file system is not found in /etc/fstab, check if they are
mounted otherwise (e.g. via systemd mount units).
