Under NT? The permissions set on the parent directory. But this
is really MS documentation.

Sorry, wrong description. On NTFS it always uses the RID then which
is substituted by a name in `ls -l' output iff /etc/passwd has a
corresponding user entry.

On FAT it always assums the current user is the owner regardless
of the ntsec setting.

mkpasswd didn't that up to Cygwin-1.1.5-4, it does from 1.1.5-6 on.
But it _never_ uses another login name than the one which is given
by the NT system (locale dependent). If you want that Cygwin sees
admins as root, _you_ have to change the name like the aforementioned
`myadmingrp' example.
