[RFE] [PATCH] star vfs and xattr feature request

[Jindrich Novy <jnovy redhat com>]

Hello mc-devel,

Curtis Doty sent me a patch for star vfs support, where he says:
-------------------------------------------------------------------------------
Here's a patch that attempts to add star filesystem support. Which is
fairly important IMHO now that Fedora is using selinux (or anything that
uses extended attributes).

Star also seems very forgiving; allowing the same view/extract command to work
across native archives or those compressed with various programs.

However, I couldn't get #utar to work so had to write the little #ustar script;
which is dog slow. So I'm hearby requesting a new feature: can the #utar extfs
be made to extract from starchives that contain selinux security descriptors?
-------------------------------------------------------------------------------
