Please enlighten me. To me it looks as if cygwin or at least mkpasswd formerly used 513 as the gid for "None", and switched to 197121 at some point. I currently do not understand this: Before I changed gid of my user from 513 to 197121 in /etc/passwd, ls printed 513 as the group of files in the home directory. After the change, ls prints "None" as the group. But 197121 is the id of None. At first sight, this looks like the file group ownership has changed from 513 to 197121, but I do not see why that should have happened. >> No doubt. So what kind of maintenance do these files need?

Does this mean that if /etc/passwd exists, /etc/group must also exist (and match)? Or that, if /etc/passwd gives a currently-non-canonical gid such as 513, /etc/group must exist and define that gid?
