Script to clean recordings from OpenATV (Enigma2) STB recordings dir. Recordings are removed oldest (based on lexical sort) first, untill at least min_space is free on hd device.
Perl on OpenATV (opkg package) is rather limited (no (even core) modules
present apart from strict, warnings and Config. So everything has to
be done in a rather DIY basic way.
Seems that every facility.severity is being forwarded to remote syslogd
by logger. So system('logger', .... should be enough.
