Yes, but you shouldn’t.
After a reboot, a lot of phones can only use the device’s default keyboard app for entering the unlock pin/password.
If you’ve removed or disabled it, you can get into a situation where you have no keyboard at all, and a delightful chicken-and-egg situation of needing a keyboard you don’t have until after unlocking the device to enter the code to unlock the device.
(A USB keyboard will let you escape this, for what that’s worth)
Generally, you just need to export the pool with zpool export zfspool1, then import again with zpool import -d /dev/disk/by-id zfspool1.
I believe it should stick after that.
Whether that will apply in its current degrated state I couldn’t say.
While I have a personal general rule against backing electronics on Kickstarter and would likely wait for it to be available at retail, I wouldn’t necessarily immediately discount this one.
It’s probably worth noting - mentioned in Jeff Geerling’s video - they had a MOQ of 1500 on the metal case, which likely forced them to be significantly further through the process than a lot of Kickstarters are at launch.
When I got my new phone recently, I asked of it what is by a wide margin my most common voice task; setting a timer for something I was cooking.
It presented a UI suggesting it had understood the assignment, but utterly failed to actually set the timer.
It was at that point I reverted to Assistant and forgot it existed.
This feels par for the course though; a bunch of effort spent on a few “hard” tasks to make it seem impressive, but zero on maintaining existing functionality that normal people actually use on a regular basis.
