Re: Can't find bootable partition

I booted the 14.0-RELEASE installer and mounted zroot to /tmp/mnt.

There's nothing in the zroot, except other mounts (like /usr, /home, and /var, the defaults). Those appear to have good data. But there's no /tmp/mnt/COPYRIGHT, /tmp/mnt/boot, etc.

I did a very lengthy memtest on this machine without issue. I don't have any particular reason to suspect hardware.

It's as if every file/folder directly under zroot/ROOT/default has vanished.

There's no zpool errors.

I made no changes to the filesystem in the boot prior to the reboot.
