# User notes
# ----------
#
# This package provides both libraries and utilities. Some libraries like
# libuuid, libblkid are dependencies of other packages. Vanilla does not split
# util-linux in different packages like many distribution do.
#
# Since util-linux tools override busybox utilities, users who only want
# util-linux libraries may specify the COMPONENTS option to either "no" or a
# space-separated list of individual components to build.
#
# Example:
#
# COMPONENTS="no" (only build libraries)
# COMPONENTS="fdisk mountpoint" (will build libraries, fdisk and mountpoint)
# COMPONENTS="yes" (will build almost everything, the default)
#
