Found out some cool make targets by chance..

- From /usr/src/Makefile:

# universe            - *Really* build *everything* (buildworld and
#                       all kernels on all architectures).
# buildworld          - Rebuild *everything*, including glue to help do
#                       upgrades.
# installworld        - Install everything built by "buildworld".
# world               - buildworld + installworld.
# buildkernel         - Rebuild the kernel and the kernel-modules.
# installkernel       - Install the kernel and the kernel-modules.
# installkernel.debug
# reinstallkernel     - Reinstall the kernel and the kernel-modules.
# reinstallkernel.debug
# kernel              - buildkernel + installkernel.
# update              - Convenient way to update your source tree (cvs).
# check-old           - Print a list of old files/directories in the system.
# delete-old          - Delete obsolete files and directories interactively.
# delete-old-libs     - Delete obsolete libraries interactively.
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
# command line. By keeping this makefile simple, it doesn't matter too
# much how different the installed mk files are from those in the source
# tree. This makefile executes a child make process, forcing it to use
# the mk files from the source tree which are supposed to DTRT.
# The user-driven targets (as listed above) are implemented in
# If you want to build your system from source be sure that /usr/obj has
# at least 400MB of diskspace available.
# For individuals wanting to build from the sources currently on their
# system, the simple instructions are:
# 1.  `cd /usr/src'  (or to the directory containing your source tree).
# 2.  `make world'
# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
#  1.  `cd /usr/src'       (or to the directory containing your source
#  2.  `make buildworld'
#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is
#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is
#  5.  `reboot'        (in single user mode: boot -s from the loader
#  6.  `mergemaster -p'
#  7.  `make installworld'
#  8.  `make delete-old'
#  9.  `mergemaster'
# 10.  `reboot'
# 11.  `make delete-old-libs' (in case no 3rd party program uses them

So, this helps a bit when updating your system. Didn't realize that the
delete-old and delete-old-libs make targets existed, nor kernel..
