Well, so I'm getting ready to install the first set of patches on my x4500
since we deployed into production, and have run into an unexpected snag.

I already knew that with about 5-6k file systems the reboot cycle was going
to be over an hour (not happy about, but knew about and planned for).

However, I went to create a new boot environment to install the patches
into, and so far that's been running for about an hour and a half :(,
which was not expected or planned for.

First, it looks like the ludefine script spent about 20 minutes iterating
through all of my zfs file systems, and then something named lupi_bebasic
ran for over an hour, and then it looks like it mounted all of my zfs
filesystems under /.alt.tmp.b-nAe.mnt, and now it looks like it is
unmounting all of them.

I hadn't noticed before, but when I went to check on my test system (with
only a handful of filesystems), but evidently when I get to the point of
using lumount to mount the boot environment for patching, it's going to
again mount all of my zfs file systems under the alternative root, and then
need to unmount them all again after I'm done patching, which is going to
add probably another hour or two.

I don't think I'm going to make my downtime window :(, and will probably
need to reschedule the patching. I never considered I might have to start
the patch process six hours before the window.

I poked around a bit, but have not come across any way to exclude zfs
filesystems not part of the boot os pool from the copy and mount process.
I'm really hoping I'm just being stupid and missing something blindingly
obvious. Given a boot pool named ospool, and a data pool named export, is
there anyway to make live upgrade completely ignore the data pool? There
is no need for my 6k user file systems to be mounted in the alternative
environment during patching. I only want the file systems in the ospool
copied, processed, and mounted.

<fingers crossed> Thanks...
