# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM

# Explode the package framework:
cd $PKG

# Apply some of the generic Slackware packaging policies:
slackdesc       # install slack-desc

# Install package post installation script:
mkdir -vpm755 $PKG/install

# Allow root login on some of the known ARM serial consoles device names:
# The install script used to check the machine type during installation, and
# append the appropriate device names, but now it's a static list which
# could be moved back into this script.  However, it serves as a useful reminder
# should I want to go back to the previous way (unlikely though as it causes
# problems for the 'miniroot' since the machine building the root isn't the
# same as those for which the package modifications may be intended).
install -vpm644 $PORTCWD/sources/doinst.sh.serialconsole-allowroot $PKG/install/doinst.sh
# Append the standard (non ARM) post installation script:
zcat $CWD/doinst.sh.gz | sed -e 's?^#!.*??' >> $PKG/install/doinst.sh

slackgzpages -i # compress man & info pages and delete usr/info/dir
slackmp         # run makepkg -l y -c n

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