I've found it extremely common that software needs to be installed into /opt - sometimes via pkgadd and sometimes otherwise. If software is installed via pkgadd, single-zone installation of software is just broken with an inherited /opt. If it is installed via another mechanism, you can mount other file systems on subdirectories of /opt - but means that you have to create the mount point in the global zone. This has the potential to complicate zone migration and causes confusion for those that are already struggling with zones and inherited directories. -- Mike Gerdts http://mgerdts.blogspot.com/ ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] how long would it take to install a zone on Sun
I have scripted out my zone builds for consistency and to make site specific additions to the new zones post install. Assuming the zone root filesystem is on a different disk from the OS, it takes about 15 minutes to create a sparse zone and 25 minutes to create a whole root zone on an E2900. That includes the config, install, initial boot of the zone, and about 1 minute of site specific post-install setup in the zone.

Because we can't upgrade zones living on zfs filesystems (yet) we left this feature out of S10 U4. It is, however, in Nevada. -dp -- Daniel Price - Solaris Kernel Engineering - [EMAIL PROTECTED] - blogs.sun.com/dp ___ zones-discuss mailing list zones-discuss@opensolaris.org

That is not my experience, and I just tried it on build 12 (not GA version), and it did not create a ZFS snapshot nor a clone of that snapshot. This partial ZFS list shows the difference between S10 and Nevada. I just cloned a zone who's zonepath is in /zones.

It is faster with the zonepath on ZFS, but clones are relatively fast on UFS as well. At least sparse zones. On my laptop about 30 seconds or so, last time I actually payed attention. Compared to five to ten minutes if not a clone. What I like about cloaning is that the SMF repository is copied. The initial boot of a cloned zone is the part I really appreciate being accelerated. Plus all the customizations also carried over, of course. On ZFS, with Nevada, a snapshot and then clone is created, so it is very fast.

Re: [zones-discuss] how long would it take to install a zone on Sun
After reading some material about zoneadm clone, it seems to me that such a fast zone creation requires the template zone to be on a zfs file system. However, if not, anything else can help speed up installing zone? Especially, at present, my SUNOS only have a global zone.

The use "zoneadm clone". Since you are on an OpenSolaris list, I'm assuming that you are not running Solaris 10. If this is the case and your template zone has a zonepath at the root of a zfs file system, clones can be created in seconds. The variant of the code that I wrote[1] (which doesn't do sysidcfg) could do it in less than a second on the slowest machine that OpenSolaris supports. 1. http://mgerdts.blogspot.com/2006/02/zone-created-in-0922-seconds.html -- Mike Gerdts http://mgerdts.blogspot.com/ ___ zones-discuss mailing list zones-discuss@opensolaris.org
