- Do the two files compare (cmp) identical?

- Please send me details (e.g. create a script file and send it). I noticed
- a problem on initial reboot with socket inode types, but this vanished
- after the first fsck and did not perpetuate (I assume that the binary
- dump has some unecessary socket inodes on it that cpio is not
- recreating properly, thus a nuisance).

- Currently, the system does not do the correct thing with fresh badblocks,
- partially due to new work in the wd driver that alters the way that
- retries work.

- It's not. It means that the VM system saw that the page was modified
- after an attempted write to disk (it was dirtied by a program accessing
- it). For the moment, consider it a soft error. Much more is involved here,
- and I especially want to here if this happens more than sporadically on
- systems with > 4MB of RAM, but for the moment ignore this diagnostic.

- Don't worry, the sky is not falling (yet) !
