In the old days I tried NFS root does that count ? :D

On my old WRAP (http://www.pcengines.ch/wrap1e203.htm) I have:

FAT16 on the CF card, with squashfs for the root file system and the 
unionfs with a tmpfs and the squashfs from above
Then the root gets changed with pivotroot into the union so I get a 
read/write root

I've also added an "rc" script located in the FAT16 so I can alter little 
things (update exe/libs etc) at start up without creating another squashfs

I'm not sure what casper does (do you have a URL?) but if you're going to 
write the changes back to the same USB what's the advantage over a normal 
read/write file system?

I don't bother with logs, but you could syslog them remotely.
