Solved Mounting zfs drive from an install key

[JozanOfAstora]

Hi, I've set some bad options in my /boot/loader.conf and now my system keeps rebooting into kernel panic.

I have a 13.1-RELEASE install key and I'd like to mount my zfs drive to /mnt to simply remove a few lines. What is the quickest way of doing this?

zpool list gives nothing

On a running system you have physically access do init 1 which drops you into single user mode or ESC from loader menu.

See "Manual booting" there: https://forums.freebsd.org/threads/installing-freebsd-manually-no-installer.63201/

Of course I've set boot_delay to 1s and beastie_disable to YES and I have no shell access anyway. The system boots, asks for my encryption key, the kernel crashed when loading the bad modules and just keep rebooting

It's probably easier for you if you just boot from the install media, and choose "Shell". Then you can load the geli(8) key, import the zpool (make sure to add -R /mnt), mount the filesystems and remove the offending modules/settings from your loader.conf.

There are ways to do this from the loader prompt but even seasoned FreeBSD users will have trouble with this.

This is precisely what I'm trying to do right now but I can't find my zpool anywhere

It's encrypted. You need to unlock it first with geli(8).

That's right I forgot about this! Thanks a lot for the reminders, I managed to do fix everything
