Oops, I’m mixing the zpool and zfs commands. It’d be “zpool import”.
And you do this just once: afterward, the automatic on-boot import brings the
drives back in using the names they had before, so

you can reflash SOME
in large raids, I label my disks with the last 4 or 6 digits of the drive
serial number (or for SAS disks, the WWN).this is visible via smartctl,
and I record it with the zpool documentation I keep on each server
(typically a text file on a cloud drive). zpools don't actually care

With ZFS, you set a partition label on the whole-drive partition pool member,
then mount the pool with something like “zpool mount -d

When was the last time you tried it?
Why would you expect that a modern 8-core Intel CPU would impede I/O in any
measureable way as compared to the outdated single-core 32-bit RISC
yeah .. it would need to run X11

you can't run it? or can't find it?
if it doesn't want to run, it probably is because you're not forwarding
X11 in your server, in this case your mac. the ssh server nees to
do/allow that
what about executing it remotely :
ssh -X myuser@theremote-mac "open -a Firefox" ?
if that
I can ssh -X myuser@theremote-mac
but I cannot run /usr/bin/firefox.
I can run "open -a Firefox" on the mac but then it just opens firefox on
the mac
Thoughts?

I'm trying to setup an ssh tunnel so I can run firefox on a remote
