Just curious if anyone has played around with switching boot
environments on OpenSolaris DomUs.
For example, in an OpenSolaris DomU, I can update the software with a
"pkg image-update". This will create a new boot environment and schedule
it to be the current BE on next reboot. This actually works well.
What I haven't played with is how I can switch to a previous BE, if for
example the new BE fails.
At least with a paravirtualized OpenSolaris guest, I don't see the
typical GRUB boot menu with all the different BEs listed. So I'm curious
how one might boot from a different BE in this case.
Thanks..
