- replace logger with $LOGGER, which is defined to `logger -t apm'
- use 'mount -u ... -A -t ffs' instead of 'mount -u ... -a', since the
latter won't work on already mounted file systems except for `/'.
* Move audioplay to a shell function, to have one location where to
change the noise-making
* use /etc/rc.d/dhclient instead of doing it manually
* when going line->battery and vice versa, adjust idle timeouts of
harddisk (atactl), and add noatime,nodevmtime mount options.
