Don't use an SD card? Seriously, pulling the power on an SD card has
been known to corrupt it beyond recovery. BUT.
Is the big worry that the home directory will get corrupted etc etc? I
don't know if you can partition an SD card, but look at doing a
kiosk-style install with the OS protected and read-only. Then look at
sticking a loopback device on top of home, so that any changes exist
only in ram, and are lost on shutdown. Hopefully, that means you now
have a system that can boot and run off a write-protected SD card :-)
Look at the raid wiki site
https://raid.wiki.kernel.org/index.php/Linux_Raid#When_Things_Go_Wrogn
and especially the stuff on recovering a damaged raid for info about how
to set up loopback.
