Re: [libvirt] Bump tar format?

> Since RHEL5 support has been dropped for a while now, maybe it's time to > revisit changing the tar format Yep, IIUC we should be fine for require pax support for the vintage of Linux we required.  *BSD should be fine too, so IIUC, their tar version uses libarchive which supports pax.  Windows has 7-zip which can do pax and of course cygwin. Finally OS-X has the pax command and support in the apple archive utility. So I think we're be fine to require it. While, we're changing this, I think we should probably take the opportunity to also switch over to using 'xz' as our compression format, instead of gz. Consider the 1.3.5 release compressed with different formats:  35109092  libvirt-1.3.5.tar.gz  25573966  libvirt-1.3.5.tar.bz2  12112612  libvirt-1.3.5.tar.xz Those results seem pretty compelling to me :-)
