How to change passphrase for FreeBSD 11.0 encrypted ZFS root?

[Jov]

Not a ufs?
What's the output of gpart show?

Thank you for the clue.


I would now like to edit /boot/loader, to see if I can adjust the settings
so that GELI will decrypt my root partition using just a passphrase.


When I boot the FreeBSD 11.0 i386 installer into single-user mode:

# mount /dev/ada0s1a /mnt
mount /dev/ada0s1a: Invalid argument


Why is mount(8) complaining?

# ls -l /dev/ada0s1a
crw-r-----  1 root  operator  0x5b Jun 14 15:53 /dev/ada0s1a
