This is not a result of a failure of star.
The fact that star currently does not support all zfs properties has several
reasons:
- The ACL library interface in libsec was wrong in the first version
because people did hot ask me how such a library interface needs to
look like.
- I have been unable to find discussion partners to develop a useful
archive format for extended attributes. The archive format used by Sun
tar is not useful as it is based on an outdated TAR extension machanism
defined by POSIX in 1988. The format from Sun tar is not extensible and
it is not detectable. new features of course need to be implemented
using (detectable) methods from POSIX.1-2001.
- Finally I was waiting a long time with the star-1.5final release
because
I thought I may need to change things for the star Solaris integration.
Unfortunately it turned out that collaboration at that point did not
work. As a result, star-1.5-final has been published 6 weeks ago.
Once there is a will for collaboration, things may change quickly....
Star has been designed to be extensible without limitations.
