Sparse root zones do not exist with OpenSolaris. When you use zonecfg's "create" (without -b), the file /etc/zones/SUNWdefault.xml is used as the initial configuration for the zone. With "create -b", /etc/zones/SUNWblank.xml is used. On OpenSolaris, these files are the same because the new packaging system does not support sparse zones. In Solaris 10, SUNWdefault.xml listed /usr and several other directories as inherit-pkg-dir. Thus, the zones were sparse. SUNWblank.xml listed no inherit-pkg-dirs. Sparse zone support was just fully removed from the source: http://bugs.opensolaris.org/view_bug.do?bug_id=6939693 http://hg.genunix.org/onnv-gate.hg/rev/76969fc28795 In earlier days (such as a year ago when the release you are using was new), it seemed as though there was some interest in continuing to support sparse root zones with the ipkg brand (but no code released to support it). However, other factors have made sparse zones less important than they were 5+ years ago when Solaris 10 was released. Those that I have observed are.... - The new packaging system tends to lead to smaller installations by default - Typical hard drives are much larger - ZFS compression and deduplication can reduce the disk usage -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list firstname.lastname@example.org
