Tahrpup 6.0.2 flashdrive install, running on Thinkpad T61

In snapmergepuppy under WHITEOUTS the statement that begins 'find . -mount ' hangs under ceratain conditions. Changing the '.' to 'root/' fixes it, but I suspect will miss some. Is "find" having a problem, or what?
I edited in some "echo" statements to try to trace this, and this is the best I can find. HELP!
Oh - I applied the quickpet to 6.0.5 and we'll see, but snapmergepuppy has not changed.

I did some more digging.
After Thuderbird does an automatic update, a directory is created/updated/changed in /initrd/pup_rw/ called .wh..wh.orph which seems to cause all sorts of mischief. Trying to "ls -a" on this causes a hang. Trying to even see it in ROX makes ROX hang. I don't know what is supposed to be in there, but it is problematic.

OK, something very bad happens to /initrd/pup_rw/.wh..wh.orph when Thunderbird does an update. That update happens automatically when I start Tbird. (And I cannot see what it does) After, I cannot do an ls /initrd/pup_rw/.wh..wh.orph, I cannot rm- r it, I cannot rmdir it, I can't even "touch" it without a system hang (with high cpu use). This is serious, since I can't do a shutdown with proper save because snapmergepuppy hangs as well.
I tried manually running thunderbird in a console to see what the update does, but no good. HELP!

I invented a work-around until the next time Tbird wants to update.
I temporarily modified snapmergepuppy by changing the statements that begin with 'find . -mount' to 'find /initrd/pup_rw/opt -mount'
Then allowing Tbird to do the update and ONLY THAT, then rebooting. The whiteout files that went with Tbird (which reside in /opt/thunderbird) were correctly processed so that the update "stuck" and the original form of snapmergepuppy could do its job for future shutdowns.
I still have no clue what happens to .wh..wh.orph during the update, and a permanent fix would require that this be understood, so any insights would be appreciated. So this problem is NOT closed for now.

The problem also occurs on upgrading firefox. /initrd/pup_rw/.wh..wh.orph is really wierded out; I can't tell why. stat reports all is normal, but i can't do anything (including look inside) this dir. after the upgrade.
Can anyone tell me what this dir is supposed to contain, and what its function is?

I upgraded Firefox to version 44 without the problem. I guess Mozilla fixed the upgrade process. I still would like to know what the h*** happened!
Consider it closed by default.

*.wh.* files are *.whiteout.* files and dirs of the AUFS filesystem to mark deleted files .

When such .wh. marker file is created, the real file cannot be modified anymore .

I am running normal traditional full installations mainly,
which has no use for a union-file-system like AUFS by default,
and do not bother much with them anymore.

My thinking is that such update process first deletes existing files ,
which makes the AUFS driver creating these .wh. marker files.

It would be better if the files would be forcibly overwritten .

From memory I remember I tried once to move /etc/rc.d/PUPSTATE to /etc/rc.d/PUPSTATE.previous in rc.shutdown,
which created such .wh. marker file for /etc/rc.d/PUPSTATE .
That led at next boot to be unable to create a new /etc/rc.d/PUPSTATE file, thus creating lots of hassle.
