I have had no non recoverable error here up to now, but I am not
representative, since I do not need many permanent writes: I have all
permanently changeable informations like configuration files in one rw
partition, and all temporary information like log, lock, pidfiles... in
the ramdisk. My rootfs stays ro. In my case, I can simply erase the
"config-partition", and the board definitely is clean.
I have 2 ideas to your problems:
1. Single files can be still corrupted, when you write them and press reset.
2. Your jffs2 version is from a let's say "not so good time"
What I do not understand (from one of your previous posts): You said, a
command file was damaged. Was this file written at generation time of
the fs, and then not written any more?
