If that only complaints about root directory permissions, you may reset them. Just don't touch permissions inside Cygwin installation root. In regard to canonical order of permissions, some (some!) of the POSIX permission combinations can't be correctly represented in any other way, and there's no reason permissions MUST always be in canonical order. It's a convention, not a requirement. But many a tool are unable to deal with permissions not in a canonical order and you must be very careful when seeing such alert. Reordering permissions in such case may actually make things worse. -- With best regards, Andrey Repin Saturday, November 13, 2021 19:08:43 Sorry for my terrible english...
