No Mike, you can write to the ramdisks, even change the dnetc -config, or the netconfig prams, but it's gone after a shutdown and isn't saved.
The floppy remains the same as the frist time you used it.
Klinux is loading the Linux kernel first, then it finds and uncommpresses the file system into memory.
This way, you can pull the floppy out after booting a node, and put it in the next one.
I don't know if you read the Wordpad.txt or not, but any blocks not flushed to a pproxy before shutting down will be lost.
I wrote in the instructions to only buffer about an hours worth of WUs for your perticular machine, just for this very reason.
All though, I have my original Klinux version running on my O/C'd Rack boards, running Cel 500s @ 585 on the 78Mhz bus, (the nics crap @ 80 FSB) for what seems like two weeks now.
It does seem really stable, if your not running too awfuly out of spec.
