Many arm systems don't have a rtc. This means every time they reboot the
clock goes back to the epoch. Clocks going back to the epoch causes all
sorts of issues (some versions of fsck fail, make won't work properly,
logs will be impossible to relate to each other, and very annoying
forced password changes).
There is NTP of course but that doesn't typically kick in until quite
late in the boot process (unless the boot process is hacked to bring up
the network real early) because it depends on network. Also not all
systems will nessacerally have network access all the time.
So i'm wondering about implementing a "fake-rtc" that simply saves the
time to somewhere in /var on shutdown and reloads it on bootup. The time
would still be wrong until/unless something else syncs it but at least
it wouldn't go backwards.
Do others think such tool is a good idea.
Would there be any chance of getting such a package in debian (note: i'm
not a dd so someone would have to sponsor it)
