# This PKGBUILD was generated by the archzfs build scripts located at
#
# http://github.com/archzfs/archzfs
#
# ! WARNING !
#
# The archzfs packages are kernel modules, so these PKGBUILDS will only work with the kernel package they target. In this
# case, the archzfs-linux-zen packages will only work with the default linux-zen package! To have a single PKGBUILD target many
# kernels would make for a cluttered PKGBUILD!
#
# If you have a custom kernel, you will need to change things in the PKGBUILDS. If you would like to have AUR or archzfs repo
# packages for your favorite kernel package built using the archzfs build tools, submit a request in the Issue tracker on the
# archzfs github page.
