It isn't not only decompressing. First it has to extract in RAM the compressed
filesystem residing on disk.

Only a guess : maybe your floppy has bad blocks. That's why there is a
problem. But normally, ./mu -i should have warned you when formatting, and
then verifying. However, as it isn't a fatal error, you still may have mu -i
terminating by "ok, reboot your system and have fun" although there were bad
blocks on the disk, which prevent mu to work properly.

I am not so sure that it would be so good to have raw mulinux images, as
standard mulinux requires floppy to be formatted in 1722k.
But if you really want to do this by hand, format your disk and do a
cat BOOT ROOT.gz USR.bz2 > /dev/fd0
it should work with standard mulinux. There is no mystery, it is what ./mu -i
does. But it turns to be a bit harder with other setups than BOOT/ROOT/USR on
a single 1722k floppy, so it remains better to let ./mu -i do the job.
And still "./mu -i\n\n\n" remains simpler than "fdformat /dev/fd0H1722 \n cat
BOOT ROOT.gz USR.bz2 > /dev/fd0\n". (\n stands for a newline...).
