I looked over the dir I'd been using and went to create a test case. Decided to create symlink to one of the tools in the sysinternals toolbox. cd'd to the dir to pick up the path in 'T': /progd/Microsoft/Windows/Start Menu/Programs/Menus/Tools/Sysinternals/SI /progd/Microsoft/../Sysinternals/SI> T=$PWD made test dir and put a link in it to a tool in the dir: /tmp> cd test /tmp/test> ln -s "$T/Desktops" . /tmp/test> ll total 0 lrwxrwxrwx 1 81 Jul 3 13:48 Desktops -> /progd/Microsoft/Windows/Start Menu/Programs/Menus/Tools/Sysinternals/SI/Desktops test it... C:\tmp\test>tar cf /dev/null --acls --xattrs --sparse "-b 2048" --one-file-system . tar: Desktops: Warning: Cannot llistxattrat: Permission denied -- looks similar, strace output attached. I don't know if this is an instance of the same error or a different one -- I say that because when I look at the link I created in /tmp/test using cmd /c dir, I get: ... Directory of C:\tmp\test 2021/07/03 13:48 Desktops [...] ....it's a junction?? (That wasn't the case before -- ahh it was because the target didn't exist...). Trying again but adding .lnk, so dir shows: 2021/07/03 14:53 Desktops [C:\progd\Microsoft\Windows\Start Menu\Programs\Menus\Tools\Sysinternals\SI\Desktops.lnk] Maybe the strace will confirm, but I think if a symlink target isn't accessible when tar archiving the symlink, maybe that's when the problem pops up. Accessibility has to mean not only present, but possibly allowed by perm settings -- which aren't set right by cygwin even for cygwin's own use...(separate email to come)...
