I'm using Linda' script that does that, but here's the raw getfacl
output for 2 folders created in C:\ Note they have very different
$ getfacl /cygdrive/c/Test-dir-created-in-cygwin/
# file: /cygdrive/c/Test-dir-created-in-cygwin/
# owner: GAF
# group: None
$ getfacl /cygdrive/c/Test-dir-created-in-file-explorer/
# file: /cygdrive/c/Test-dir-created-in-file-explorer/
# owner: GAF
# group: None
That last one with the directory created via file explorer has truly
bizarre (to me) ACLs. Normal? If not, how do I fix it.
Note I have 2 different Win 7 boxes showing this same behavior.

hmm..... I think that is a "root" group, not a "root" user.
I seriously doubt I created a root as a group. Are you sure that
isn't standard with cygwin?
note: I love using cygwin, but I'm not very knowledgeable about user
and group management in cygwin. On the other hand, I'm pretty good at
it in Linux. (I'm a 30+ year UNIX/Linux user)

If I did, I will try to avoid it in the future. This e-mail is
interspersed. I assume that is desired.
