# Install into package:
install -vpm755 src/cryptsetup $PKG/sbin/cryptsetup.static

# Now that we have the .static version, it only makes sense to
# use it by default (even when calling /usr/sbin/cryptsetup).
# This avoids missing library issues if someone installs an
# encrypted system using only the A package series.
#
# This is small, so save it:
mv $PKG/usr/sbin/cryptsetup $PKG/usr/sbin/cryptsetup.dynamic
# Replace with a link:
( cd $PKG/usr/sbin ; ln -vsf ../../sbin/cryptsetup.static cryptsetup )
# Put one in /sbin too, in case someone tries to use /sbin/cryptsetup:
( cd $PKG/sbin ; ln -vsf cryptsetup.static cryptsetup )

# Copy docs:
DOCS='AUTHORS COPYING* ChangeLog INSTALL NEWS README TODO'
mkdir -p $PKG/usr/doc/$PKGNAM-$VERSION
cp -favv $DOCS $PKG/usr/doc/$PKGNAM-$VERSION/

# If necessary, start the fakeroot server so we can set file/dir ownerships:
start_fakeroot

# 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      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
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
