Manual Pages  — ZFSBOOTCFG

zfsbootcfg is used to set boot.config(5)-style options to be used by zfsboot(8), gptzfsboot(8) or loader(8) the next time the machine is booted. Once zfsboot(8) or gptzfsboot(8) or loader(8) reads the information, it is deleted. If booting fails, the machine automatically reverts to the previous boot configuration. The information is stored in a special boot environment area of a ZFS pool.

If used without arguments, zfsbootcfg will output the current boot configuration, if set.

The following options are supported by zfsbootcfg:

-k key
	Define key for <key, value > pair.
-n name
	Update nvlist name.
-p
	Print all information stored in ZFS pool bootenv area.
-t type
	Set type of value used in <key, value > pair. Currently supported types are:
DATA_TYPE_BYTE DATA_TYPE_INT8 DATA_TYPE_UINT8 DATA_TYPE_INT16 DATA_TYPE_UINT16 DATA_TYPE_INT32 DATA_TYPE_UINT32 DATA_TYPE_INT64 DATA_TYPE_UINT64 DATA_TYPE_BOOLEAN_VALUE DATA_TYPE_STRING

If not specified, the default is DATA_TYPE_STRING.

-v value
	Define value for <key, value > pair.
-z pool
	Operate on pool.
