ZFS installer fails on the SG-2220 due to the small size of the internal storage (4 GB). The default swap size in ZFS is 2G but reducing this still results in a failure. The install appears to go through properly but after a reboot we get this error:

Mounting from zfs:zroot/ROOT/default failed with error 5.

Loader variables:

Manual root filesystem specification:
  <fstype>:<device> [options]
      Mount <device> using filesystem <fstype>
      and with the specified (optional) option list.

    eg. ufs:/dev/da0s1a
        cd9660:/dev/cd0 ro
          (which is equivalent to: mount -t cd9660 -o ro /dev/cd0 /)

  ?               List valid disk boot devices
  .               Yield 1 second (for background tasks)
  <empty line>    Abort manual input

mountroot> da0 at umass-sim0 bus 0 scbus6 target 0 lun 0

panic: mountroot: unable to (re-)mount root.

KDB: enter: panic

The installer should check storage and memory capabilities to ensure ZFS isn't installed on a system with insufficient storage/memory requirements. The user should be alerted if the minimum size is not met. Documentation should be updated to reflect this.

Per Renato, this likely affects FreeBSD stock.

error is still there for me on SG-2220 with 2.4.4 CE
Even when I reduce the swap to 0.
