Description

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:
  vfs.root.mountfrom=zfs:zroot/ROOT/default

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

    eg. ufs:/dev/da0s1a
        zfs:tank
        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

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.
