The init on the CF bootstraps the system by running sanity checks on the disk. It then does one of two things #1 If the sanity check passes, chroots (it was pre the root swivel stuff) and execs /sbin/init. #2 If it fails, it rebuilds the disk environment from the flash and puts everything there. That wasn't trying to save configuration changes merely to restore a pre arranged 'boot' configuration off the CF. > Q3: Are there any filesystems that are better for Flash, in that they > "spread" the writes across multiple blocks? > Ext3 and any other journalised FSs should be avoided, right? (due to > concentrating lots of writes in the journal) Decent CF cards use wear levelling (its actually log structured internally). If you buy your CF from Micron (ie crucical) it comes with a lifetime warranty so it's their problem 8) Also for maximum reliability turn off the write cache on the hard disk.
