I have a problematic set of ACLs that is causing Cygwin to not behave
(and it's not Cygwin's fault). I recently had to do a
format/reinstall of XP (yes, even with XP it's sometimes easier to
just pull the trigger). In my setup, I only put the OS (and such
Microsoft programs that don't ask) on the C partition. I put
programs, data, etc. on D through G. What I didn't realize was that
all user/group SIDs have embedded in them the machine SID. And that
SID changed when I reinstalled. I discovered the hard way what
happens when you don't save that little bit of info. I finally
figured out a way to force the change and/or removal of all ACLs that
have invalid SIDs (through the W2K resource utility SUBINACL). So
everything was now pointing to valid SIDs. But I didn't stop there.
I figured that it'd be easier in the future if all files inherited
their attributes from the root ACLs
Apparantly, Cygwin does not like this. I did the standard Setup.exe
install. Then brought up bash. No /etc/passwd,group files. No
rights to anything. The following directory listing fragments were
found:
bash-2.05b$ ./ls -aln /cygdrive/d/cygwin

Questions: Why is everything coming up with no rights? And I assume
the 65535 group entries indicate that I must've missed a couple of
SIDs. But there's nothing in the Windows file/folder security tab
(including advanced) that mentions the ownership group -- just the user?
