# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # set standard Slackware file/dir permissions and ownerships

# Make state directory # (not really needed as rpcbind does this on startup)
# This is lower down due to the "slackslack".
# The ownership here is an exception to the normal Slackware packaging
# standards:
mkdir -vpm755 $PKG/var/run/rpcbind
chown rpc:root $PKG/var/run/rpcbind

slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
