Flaming pile of deadlocking goo when testing here, including causing
panics after it failed to mount.
Yeah, I noticed some vaguely similar behaviour on mount failures. Then I
reordered some options which seemed like they should be order independent, and
things seemed to work just fine.
Then I just now read the unionfs docs more closely, and I can see why kadischi
will not be using it in the near future.
I could probably try to track down this answer on archives of other forums, but
if you could save me the hassle-
Do rh/fedora's kernel developers foresee a working implementation of unionfs at
any point? I.e. Do they acknowlege a desire for an issueless implementation
of the same functionality, and do they see it as possible? (obviously fuse
based unionfs probably need not apply... or rather, thats a linuxrc/nash that
I'm almost afraid to contemplate)
How about the other implementation mini_fo?
-jdog
P.S. - I'll take it upon myself to experiment with how bad unionfs really is in
the context of a fedora based livecd. I just can't get over the desire to be
able to do a yum install on a livecd. I wonder how messed up things would get
doing a unionfs implementation purely with bindmounted files... (that seems
likely to be more insane than living with existing unionfs issues)
