I've put up a (newly-created) cow file on:
http://gathering.itm.mh.se/~joepal/uml/root_fs.cow.bz2 (75k)
This is created on an amd64 host running 2.6.13.3 unpatched host,
2.6.13.4-bs4 guest with ext2 file system (if that has anything to do with
it). uml_moo has not been run on the file (I tested after bzipping it,
with same results as before).
Original root_fs is a 4gb file with approx 2gb of installed data. I can
bzip that too if interesting.
Cow file is root_fs + I logged in and copied /etc/services to /root.

No, V3 is in use since long time - a lot before 2.4.24 surely.
Then there's another (minor) bug in uml_moo :-)
[EMAIL PROTECTED] /export/virtual/usermode/machine.test $ ./uml_moo
...
./uml_moo supports version 1 and 2 COW files.
Yes, saw that some time ago, too lazy to fix it.
This cow file was created on my amd64 host minutes before running the
test. It was created with 2.6.13.4-bs4.
There was no problem whatsoever with COW files before I tried to use
uml_moo. ie, they work as expected when running them.
That's why I thought
the bug was with uml_moo rather than with cow files as such.
In fact, the bug with COW files was fixed, thanks to Nix who reported it.
I could always re-do the first steps of the test and zip the cow file if
you want to take a look at it.
Yes, better tar.bz2 it (I think zip doesn't handle well sparse files).
Otherwise I think I'll simply not use COW files for now. Things work
satisfyingly well without them. :-)
