A sanity check for 'persistent store' on Knoppix from Flash

[utu]

I finally clobbered my SD Chip again, third time. .xsession-errors had nothing to do with it. I was attempting to bring in Chromium with Synaptic. Apparently over-wrote some of the system. Synaptic complained there's not enough room and quit. System in ram was obviously crippled, not responsive to command line commands. I yanked the SD Chip to avoid over-writing, but on next boot the system was obviously flawed, however minimally so. Lost some items on menu at lower left, otherwise able to post and surf, etc. Compiz still going strong. I had three ideas that have _all_ turned out not to be so. 1. I thought perhaps .xsession-errors might be eating up precious memory and causing an occasional crash; 2. I thought a crude way to avoid having to reconstitute knoppix would be to avoid an over-write on normal knoppix shut-down by yanking the SD chip; and 3. I thought some clever test might suffice to automate the intentions of thought 2. Back to the drawing board. Working within 2Gb with 250M set aside for persistent store is hazardous, given the root privilege that is ever-present in Knoppix. I'm sure Synaptic is not the only way to crash, just the latest one I've found. I still don't have an idea what I might have saved and how I might have reconstituted the system short of a full rewrite from the CD, and whether this might be preferable.
