incompat in cygwin choice of using '+' as domain and user separator.




Ran in to this trying to use tar to store acls and xattrs:

tar caf lawbins.tar scripts scripts- bin
tar: miner.js: Warning: Cannot acl_to_text: Invalid argument
tar: run-crons.sys: Warning: Cannot acl_to_text: Invalid argument
tar: smallprof.out: Warning: Cannot acl_to_text: Invalid argument
tar: tmon.out: Warning: Cannot acl_to_text: Invalid argument
tar: ubytes_to_utf8.new: Warning: Cannot acl_to_text: Invalid argument

examining one of these:

find bin -name tmon.out
bin/tmon.out

 lsacl bin/tmon.out
[u::rwx,g::rwx,o:r-x,u:Unknown+User:rwx,g:Unknown+Group:rwx,g:Administrators:rwx,g:Bliss\Domain Admins:rwx,m:rwx/] bin/tmon.out

I tried tar in an existing dir:

 mkdir test
 tar caf test.tar test
 ll test
total 0
 cd test
 tar xaf ../test.tar
 ll
total 0
drwxrwxr-x+ 1 0 Aug 22 15:26 test/
 lsacl test
[u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain Admins:rwx,m:rwx,o:r-x/ u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain Admins:rwx,m:rwx,o:r-x] test

With the above and only standard separator chars, no problem

I'm guessing, but '+' is a reserved char that's not permitted in acl_to_text...
Perhaps it might be good to not set the default to some non-default, since
the default(\) seems to work most places, including on linux, though
you do have to allow '\' in the list of allowed chars in /etc/login.defs

How do I change the default separator char from '+' back to '\'?
(by default, I mean the char that is used when the corresponding ID
isn't in /etc/passwd?

Thanks!
