This implies that the source system can be S8, S9, or S10. I don't see anywhere else in the proposal that explicitly states that S8 and S9 can be attached and upgraded, so I suspect I am reading my wishes into your words. Assuming the S8 and S9 are supported source systems, is there any real difference in the resulting zone if the following paths are taken: src-s9# lucreate -c s9 -n s10 ... src-s9# luupgrade -s /mnt/s10media -n s10 ... src-s9# luactivate s10 src-s10# flarcreate ... /net/server/src-10.flar dst-s10# zoneadm install -a /net/server/src-10.flar ... vs. (upgrade on attach - not branded) src-s9# flarcreate ... /net/server/src-9.flar dst-s10# zoneadm install -a /net/server/src-9.flar > 2) Network configuration must be adjusted depending on if the zone is > shared-stack or exclusive. > 3) NFS serving must be disabled . > 4) The vfstab must be adjusted so that local file systems from the > original > system are disabled. > 5) Any zones installed on the original system will be uninstalled and > deleted from the image (zones do not nest). > > All of these modifications happen transparently as part of the zone > installation, as is the case with the solaris8 and solaris9 brands. Will config files be removed or will services just be disabled (and hollow packages removed)? That is, will "destructive" things be done that prevent the implementation of some future v2p (e.g. zone to ldom or xen) transition? Or is it believed that the typical packages that are not appropriate for non-global zones lack configuration that would be interesting in a p2v -> v2p world? -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list email@example.com
