There are incident reports on the internet where poeple report that
fsck.(v)fat actually leads to problems rather file system fixes. Around
the time when Home Assistant OS added fsck.fat for the boot partition,
reports of empty boot partitions or file with weired filenames started
to appear. This could be caused by fsck.fat.
Disable fsck on the boot partition.
When we write the update to the boot partiton, there is nothing which
makes sure that data is written to disk. This leaves a rather large
window (probably around 30s) where a machine reset/poweroff can lead
to a corrupted boot partition. Use the sync mount option to minimize the
corruption window.
Note that sync is not ideal for flash drives normally. But since we
write very little and typically only on OS update to the boot partition,
this shouldn't be a problem.
* automatically fsck to repair partitions
* add fsck.fat so rpi boot partition can be repaired
* Use Wants= instead of Requires=
