Series [v14,01/11] package.bbclass: override tar with tar-native | expand

Commit Message

Piotr Łobacz Oct. 15, 2023, 2:57 p.m. UTC 
Extend `tar` command inside copytree() and copyhardlinktree() functions,
with additional parameters, in order to support ACLs and xattr. The posix
format doesn't need to be set in here, as GNU tar switches to it whenewer
is uses --acls and/or --xattrs parameters.

Additionaly change preservation of additional attributes for `cp` command
to all (meaning mode, ownership, timestamps etc.) not only xattrs, which
were previously.
