Please only download the latest version. You need to download the userfs distribution and apply the corresponding SuSE patch (tested with 0.9.5-pre2-patched and 0.9.7-pre2-patched). Then you compile, extract tapefs into filesystems/tapefs, make it too, and then you: mt -f /dev/st0 setblk 512 tar cvf /dev/st0 some_directory ./indexer /dev/st0 /tmp/tape-index -s insmod ../../kernel/src/userfs.o ../../utils/muserfs ./tarfs /mnt /dev/st0 /tmp/tape-index on another console: cd /mnt, and ls, access the files, etc. Known BUGS (from userfs): - ctrl-c on a process waiting for userfs finished in crash.
