I've read this document before, and it was very helpful! But it mentions
only backup via 'rename' and a new install. I understand that 'rename'
will preserve all permissions, ACL extended attributes, since the files
are untouched. But would a 'cp' also be sufficient? Or 'tar'?
In other words: is there some "black magic" in MSYS2 that stores relevant
information in extended attributes or other places, that might be lost
when not taking special care? I've seen such a problem with cygwin before
(albeit many years ago), that a file system copy and restore could lead to
lots of warnings about ownership (and even lost functionality).
Thanks for the help and all the best,
Mario
