I don't know anything about fusecompress, but I think the USB wear issue is significant. Entries in the /home directory are updated all the time. It seems that we may mount /home separately with the present standard setup, but normally, /var is also frequently updated. So at least those two, plus eventually parts of /etc should go somewhere wear-proof. For instance on a ramdisk that is initiatied at boot and written to persistent store at shutdown.
It should not be too hard to achieve this, but as I have no recent experience with ramdisks, I will only point to the possibility.
From 6.4.4 cheatcodes, we have the following choices on boot:
Code:
### Configuration / Persistent image ###
knoppix nonetworkmanager Don't start network manager
knoppix home=/dev/sda1/knoppix.img Mount loopback file for overlay
knoppix toram Copy to RAM and run from there
knoppix tohd=/dev/sda1 Copy to Harddisk and run from there
knoppix fromhd=/dev/sda1 Boot from previously copied CD-Image
knoppix bootfrom=/dev/sda1/KNX.iso Access image, boot from ISO-Image. ***)
knoppix knoppix_dir=KNOPPIX Directory to search for on the CD.
knoppix knoppix_name=KNOPPIX Cloop-File to search for on the CD.
knoppix noswap Don't use existing swap partitions
knoppix forensic Don't use swap and mount read-only
knoppix secure Disable root access
knoppix noimage Do NOT use persistent image
Maybe we could have a new cheatcode "wearproof", that copies frequently updated directories like /home and /var to ramdisk and runs from there?
