Hi,
what's the status of union-mount?
Where does the development happen - in [1]?

It's being reengineered again to take account of VFS changes that went in in
the last merge window.

On a git tree on my PC - which is occasionally mirrored in [1] when I've got
it working.

Hi,
UnionFS is a different solution than union-mount.
Checking the official GIT repositories, the last commit is from February 2012.
Can't say if the development stopped.

Hmmm, sorry for asking, but when do you plan to offer a "working"
union-mount (u-m)?
What's the status of the user-space tools or are they no more needed?
AFAICS the original authors patched e2fsprogs etc. (see Valerie's old
homepage [1]).

Development on your local workstation does not look like you do an
open development.
So, it's currently only you doing the work on u-m?

It's a maze of twisty locking problems - some of which also apply to things
like overlayfs:-(

You need to be able to tell mount(2) that you want a union. This is currently
done with a mount flag, but it might be portable to something in the mount
option string.

Yeah... I guess fsck programs need to be able to handle whiteout and fallthru
directory entries.

Excuse me. But it's quite hard to develop this on a remote git tree.
Further, I prefer not to push partially working stuff to my git tree, lest
someone pull it, try playing with it and have their fs eaten.
If someone wants it, I can mail the partially working stuff to them, but not
many people ask.

Almost entirely, yes.
