-What you may be running into is that the Chooser caches the flag settings from
-RDEV's. There is a resource in the system file called 'clst'.
-
-The effect of this is that if you built your RDEV the first time without that
-bit set then forever afterword the Chooser will ignore your new setting.

The use of "forever" is a bit strong.  The Chooser (and similarly Control
Panel) does cache some information (including, in the Chooser case, the
'PACK' flags).  The cache is validated by file creation date.  If you
replace the file with a freshly created one the Chooser will see the new
flags.  There is also a way to force the cache to be rebuilt (just for
all you RDEVers out there).  If you hold down cmd and option together
while opening the Chooser (or Control Panel) it will beep (to let you know
you can let go now) and rebuild the cache from scratch.

I hope this helps,
