systems are fully "ready to go".
'FILESYSTEMS' states: "This is a dummy dependency, for services which
require file systems to be mounted before starting." However, we have
'var' which is was run after 'FILESYSTEMS' and can mount /var if it
already isn't mounted. Furthermore, several scripts cannot use /var
until 'cleanvar' has done its thing. Thus "FILESYSTEMS" hasn't really
meant all critical file systems are fully usable.
1. Add the shutdown keyword so that the script is run at shutdown time,
and the mixer* files are saved.
2. Twiddle whitespace.
3. Remove an unecessary function, and therefore collapse one variable.
in the system on shutdown and restores the settings on boot. The settings
can also be reset to the saved values via 'mixer reload'.
