This is from the umsdos documentation:
If you don't really need dos/win95 compatibility, i.e. if you want
to compress Linux-only data, this may not be the software you want. The
msdos filesystem is extremely unsuited for fast disk access, umsdos suffers
from it too. The CVF structure msdos uses is even more unsuited, and the
time required by msdos online compression may kill the rest of Linux'
performance on these filesystems.
Just to let you know about some other online compression software for Linux:
There's a package 'double' available on sunsite for Linux online
compression. There are also compression patches for the ext2 filesystem
available under the name 'hufs' and 'e2compr'. I've also heard about a
'zlibc' project which lets you access gzip compressed files as if they were
uncompressed - it works by a patched libc. Look at common Linux ftp sites.
Like dmsdos, all those packages may have their specific advantages and
disadvantages. Please don't flame at me if the packages don't do what you
want - I haven't tested them and I don't know anything about their quatilty.
I've never done any of them, but that might help?
