There is no warning any more.
Both read-only and read-write stuff is fixed, both in
msdos-compatibile mode, and in umsdos EMD mode, and it seems stable.
-There are still few hardlink nuisances, but those are not fatal.

-I'd call it pre-release, and ask for as many people as possible to
-come and test it! See notes below for some more information, or if
-you are trying to use UMSDOS as root partition.
Userland NOTE: new umsdos_progs (umssync, umssetup, udosctl & friends) that
-will compile and work on 2.2.x kernels and glibc based systems may be found

+will compile and work on 2.2.x+ kernels and glibc based systems, as well as
+kernel patches and other umsdos related information may be found at

Legend: those lines marked with '+' on the beggining of line indicates it
passed all of my tests, and performed perfect in all of them.

Note: creating and using pseudo-hardlinks is always non-perfect, especially
in filesystems that might be externally modified like umsdos. There is
example is specs file about it. Specifically, moving directory which
-contains hardlinks will break them.

-Note: (about pseudoroot) If you are currently trying to use UMSDOS as root
-partition (with linux installed in c:\linux) it will boot, but there may be
-some problems. Volunteers ready to test pseudoroot are needed (preferably
-ones with working backups or unimportant data). For example, '/DOS' pseudo
-directory is only partially re-implemented and buggy. It works most of the
-time, though. Update: should work ok in 0.84, although it still does not
-work correctly in combination with initrd featere. Working on this!
+contains hardlinks will break them in some cases.
Note: (about creating hardlinks in pseudoroot mode) - hardlinks created in
pseudoroot mode are now again compatibile with 'normal' hardlinks, and vice
versa. Thanks to Sorin Iordachescu <sorin@rodae.ro> for providing fix.
-
-Warning: (about hardlinks) - modifying hardlinks (esp. if they are in
-different directories) are currently somewhat broken, I'm working on it.
-Problem seems to be that code uses and updates EMD of directory where 'real
-hardlink' is stored, not EMD of directory where our pseudo-hardlink is
-located! I'm looking for ideas how to work around this in clean way, since
-without it modifying hardlinks in any but most simple ways is broken!

I'm unfortunately somewhat out of time to read linux-kernel@vger, but I do
check for messages having "UMSDOS" in the subject, and read them. I might
