Check to see if you have the file

	/lib/modules/`uname -r`/kernel/fs/jfs/jfs.ko

on your system.  If so, you have jfs installed.  The system should load
it automatically when you try to mount a jfs filesystem:

	mount -t jfs /dev/(partition-name) /mountpoint

If you're creating a jfs filesystem, you need to do JUST ONE of the
following:

	# mkfs -t jfs /dev/(partition-name)
	# jfs_mkfs /dev/(partition-name)

See "man mkfs.jfs" for details on the various options.  Example:  To
build a jfs filesystem on /dev/sdb4, label it as "jfs_test" and mount
it at /jfs_test:

	# mkfs -t jfs -L jfs_test /dev/sdb4
	# mkdir /jfs_test
	# mount -t jfs /dev/sdb4 /jfs_test
