zfs discuss - Dec 2007 - how do i set a zfs mountpoint for use NEXT mount??

Folks,

Not sure if any of this is possible, but thought I would ask. This is all part
of simplifying my 2 Indiana zfsboot environments.

I am wondering if there is a way to set the mountpoint of a zfs and not have it
immediately actioned. I want this so I can set the mountpoint of my alternate
zfs boot (zpl_slim/root2) to "/" (even though I currently have an
active rootfs of zpl_slim/root ) and then have the grub bootfs parameter control
booting from one root or the other.

Are the zfs mountpoints stored in zpool.chache or ondisk or both? I was
wondering if i can tweak zpool.cache or use zdb to achieve this.

Essentially this is so the zfs filesystems under zpl_slim/root get mounted
correctly through inheritance. Currently I achieve booting from altroot by
having the roots set as legacy and referenced in the vfstab. But what this means
is the underlying zfs filesystems ( root2/opt, root2/usr, etc) dont get mounted
as they inherit legacy mode.

Any assistance would be appreciated.
