Well, I am finding I have some programs that need xattr/posix acl (not
user/group/world that is the standard). Looking at cifs mounting
options, I see that this can't happen, or so it seems, without common
unix user id and group ids between systems.
If there is any way to get S4 to cooperate with other instances to make
the uid/gids (if such isn't already done... I haven't looked enough to
know if it is local or global) and to have a way S3 has access to this,
it would be fantastic.
I am also chasing a Firefox 4 crash which is happening with a pam_mount
home directory to a cifs S4 share. It may be my screw up, it may be S4
or FF4. I will share more soon.
