to substitute the correct disk and partition name in the steps below.

You need to decide which file system to use for DragonFly install: UFS or
|
||
|
HAMMER. UFS is the classical BSD file system and HAMMER is a newer and
|
||
|
more feature rich file system, HAMMER needs 50GB space at minimum, see
|

|
'man HAMMER'. The installation is somewhat different depending on the
|

|
file system used.
