Stable File System for embedded product

Hello,

I am trying to find which file system is the best for
/etc partition on an embedded linux platform.

I am using the following file systems for linux & rootfs:-
Linux: CramFS (linux 2.4.20 denx) (read-only)
RootFS: CramFS  (read-only)

At the moment, I am using ext2 partition for /etc (read-write)
But, 1 out of  4 power-cycles of the board corrupts the
/etc partition.

Any information related to the above topic is
grately appreciated.

Regards,
S. Hebbar.
