I do not use a journalling file system. I load a ext2 fs into memory from a
raw file on DOC2000. If you loose power then you just reboot. No loss of
data. Of course only config changes not the root fs. I store config in a
shared memory sgement. I only write it to DOC when the user issues the

I am looking for some rigid means of power fail protection
for a DoC 2000 based embedded system. From what I have read
so far I understand that almost any brand of journalling file
system should do well but, then again, those readings also
mention raw FLASH and not DoC, in other words, I think I am
lost. Would someone be so kind to enlighten me?
The system in question runs on a customized 486 SoC, boots
from EEPROM and loads LILO from DoC. The kernel uses initrd
to load the M-sys supplied DoC driver.
