# Install init script:

# Fix library perms:
chmod 755 $PKG/usr/lib${LIBDIRSUFFIX}/*

# Add a documentation directory:

cp -a \
  CHANGES COPYRIGHT FAQ* README* \
  doc/arm doc/misc \
  $PKG/usr/doc/${PKGNAM}-$VERSION

# Add sample config files for a simple caching nameserver:
mkdir -p $PKG/var/named/caching-example
cat $CWD/caching-example/named.conf > $PKG/etc/named.conf.new
cat $CWD/caching-example/localhost.zone > $PKG/var/named/caching-example/localhost.zone
cat $CWD/caching-example/named.root > $PKG/var/named/caching-example/named.root
cat $CWD/caching-example/named.local > $PKG/var/named/caching-example/named.local

# This name is deprecated, but having it here doesn't hurt in case
# an old configuration file wants it:
cat $CWD/caching-example/named.root > $PKG/var/named/caching-example/named.ca

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
#slackstriprpaths     # strip rpaths
slack_delete_lafiles # delete usr/lib{,64}/*.la
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh

# rndc-confgen hangs until it receieves enough random data
# to generate its key.  Inside QEMU and on the SheevaPlug,
# there is very little happening to generate interrupts, so
# the install script hangs the installation until you start
# pressing keys or making traffic on the network card.
# Instead we'll use /dev/urandom and let the Slackware installer
# initialise the random number generator after every package
# has been installed.
# - This was fixed a while ago in the doinst.sh script.
# sed -i 's?rndc-confgen -a ?rndc-confgen -ar /dev/urandom ?' install/doinst.sh

slackmp         # run makepkg -l y -c n

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