- Since the cron job could be called before the user reboots after
install (or if log2ram is disabled), we check that the hdd log
location exists before syncing.
- Copy the log2ram.hourly sync script to cron's hourly directory on
install.
- Store sync status directly in the HDD log, to make sure we know
about it if something fails. This won't help if the HDD_LOG
variable is borked, but it'll help with everything else.
- Made sync a function to avoid repeating five lines three times.
- log2ram now requires (cp or rsync) and tee, mount, umount.
