Repackaging to deb
1. The package novell-xplatlib
  
  cd novell-xplatlib-1.0.3-39.i586/novell-xplatlib-1.0.3
  No problems here with dependencies. The postrm and postinst scripts need a bit of editing. They fiddle around with /etc/ld.so.conf, but on Ubuntu that is generated, so we create etc/ld.so.conf.d/xplatlib.conf^[30]:
```
  /opt/novell/lib
	      
```
  Then we edit debian/postinst:
```
    #!/bin/sh
RPM_INSTALL_PREFIX=
# removed because it is not the Debian way
#export RPM_INSTALL_PREFIX
#if ! grep /opt/novell/lib /etc/ld.so.conf >/dev/null; then
#       echo "/opt/novell/lib" >>/etc/ld.so.conf
#fi
/sbin/ldconfig
	      
```
  We remove Emacs backup files and build the package:
  rm debian/postinst~ fakeroot ./debian/rules binary dh_testdir dh_testdir dh_testroot dh_clean -k -d dh_installdirs dh_installdocs dh_installchangelogs find . -maxdepth 1 -mindepth 1 -not -name debian -print0 | \ xargs -0 -r -i cp -a {} debian/novell-xplatlib dh_compress dh_makeshlibs dh_installdeb dh_shlibdeps dpkg-shlibdeps: failure: couldn't find library libclnlnx.so.1 needed by debian/novell-xplatlib/opt/novell/lib/libclxlnx.so.1.0.3 (its RPATH is ''). Note: libraries are not searched in other binary packages that do not have any shlibs or symbols file. To help dpkg-shlibdeps find private libraries, you might need to set LD_LIBRARY_PATH. dh_shlibdeps: command returned error code 512 make: [binary-arch] Error 1 (ignored) dh_gencontrol dpkg-gencontrol: warning: unknown substitution variable ${shlibs:Depends} dh_md5sums dh_builddeb dpkg-deb: building package `novell-xplatlib' in `../novell-xplatlib_1.0.3-39_i386.deb'.
  
  The package can be installed and uninstalled without trouble:

2. The package
3. The package novell-xtier-base
  cd novell-xtier-base-3.1.6-12.i586/novell-xtier-base-3.1.6
  We unconditionalize (see ) the preinst, postinst, prerm and postrm.
  In preinst, we unconditionalize, and we stop /etc/init.d/regd only if it exists. And because we cannot see the difference between fresh install and upgrade, we don't exit in the upgrade case that the file distinguishes:
```
            <snip>
#if test "$1" != 1; then
echo "   doing rpm upgrade processing"
if [ "$YAST_IS_RUNNING" != "instsys" ]; then
    #echo "Novell XTier Base pre script stoping novell-xregd for upgrade"
    test -e /etc/init.d/novell-xregd && /etc/init.d/novell-xregd stop
fi
# Check if we need to export the XTier registry
# Note: We export the registry at this time to avoid losing its settings in case
# that we have to rebuild the database.
if [ -e "/var/opt/novell/xtier/xregd/db/xtier_registry.db" ]; then
        echo "   Exporting XTier Registry to temporary file..."
        rm -f /var/opt/novell/xtier/xregd/xtier_registry.xml.export
        LD_LIBRARY_PATH=/opt/novell/xtier/lib /opt/novell/xtier/bin/regutil -e /var/opt/novell/xtier/xregd/xtier_registry.xml.export
        echo "   done exporting XTier Xml Registry"
else
        echo "   Saving Pre-XFlaim registry file for upgrade..."
        cp /etc/opt/novell/xtier/xtier_registry.xml /etc/opt/novell/xtier/xtier_registry.xml.upgrade
fi
echo "done running Novell XTier Base pre script!"
# Since we cannot distinguish between fresh install and upgrade, we don't exit here in Ubuntu/Debian
#        exit 0
#fi
            <snip>
	      
```
  Because the package depends on libbfd-2.19.so, and because that isn't available in Intrepid, we do a Sneaky Symlink (TM):
  pushd /usr/lib sudo ln -s libbfd-2.18.93.20081009.so libbfd-2.19.so popd
  The postinst complains about a missing EULA for which ownerships cannot be changed. (Note that this is an alien addition to the script.) We couldn't care less about the EULA, and comment the line out.
  The prerm script just exits when upgrading, so we not only unconditionalize it, we remove the upgrade case altogether:
```
# Unconditional in Debian/Ubuntu, and no use just exiting
#if test "$1" == 1; then
#        echo "done running Novell XTier Base preun script!"
#        exit 0
#fi
	      
```
  We also replace the install_initd with an update-rc.d line.
  The same goes for the postrm:
```
# Unconditional in Debian/Ubuntu, and no use exiting or even starting a daemon
#if test "$1" == 1; then
#    if [ "$YAST_IS_RUNNING" != "instsys" ]; then
#        echo "   doing rpm upgrade processing"
#        #echo "Novell XTier Base postun script starting novell-xregd for upgrade"
#        /etc/init.d/novell-xregd start
#    fi
#    echo "done running Novell XTier Base postun script!"
#    exit 0
#fi
	      
```
  In etc/init.d/novell-xregd, the function $START_DAEMON expects the name of the daemon as its first parameter, so we change the line
```
$START_DAEMON $START_DAEMON_FLAG $DAEMON_USER $DAEMON -d
	      
```
  into:
```
$START_DAEMON $DAEMON $START_DAEMON_FLAG $DAEMON_USER -d
	      
```
  Then we do the fakeroot ./debian/rules binary and the sudo dpkg -i ../novell-xtier-base_3.1.6-12_i386.deb.
  Warning
  The pre- and postinstall scripts are not idempotent yet, but we leave that for later.
4. The package novell-novfsd
  cd novell-novfsd-3.0.0-14.i586/novell-novfsd-3.0.0
  The preinst script stops the service only when doing an install, which is apparently detected in an rpm by checking $1. We make this unconditional, for the time being:
```
# unconditionalized for .deb
#echo "novell-novfsd pre install script"
#if [ "$1" != 1 ]; then
/etc/init.d/novfsd stop || echo "NOVFSD not started"
#fi
exit 0
	      
```
  In the postinst script, we replace the RPM-style install_initd with deb-style update-rc.d:
```
#/usr/lib/lsb/install_initd -f /etc/init.d/novfsd
# Debian/Ubuntu doesn't use intall_initd, it uses update-rc.d
update-rc.d novfsd defaults
	      
```
  The prerm, like the preinst is made unconditional, and the remove_initd is replaced by update-rc.d:
```
# Unconditional in Debian/Ubuntu
#if [ "$1" = 0 ]; then
/etc/init.d/novfsd stop
#/usr/lib/lsb/remove_initd /etc/init.d/novfsd
update-rc.d -f novfsd remove
#fi
	      
```
  ... as is the postrm:
```
# Unconditional in Debian/Ubuntu
#if [ "$1" = 0 ]; then
echo "novell-novfsd uninstall script"
# Remove symbolic link to init.d script
if [ -f /usr/sbin/rcnovfsd ] || [ -L /usr/sbin/rcnovfsd ]; then
        rm -f /usr/sbin/rcnovfsd
fi
#fi
	      
```
  In etc/init.d/novfsd, we remove the rc_* functions at the end of the file: they don't exist in Debian/Ubuntu.

	Warning
The pre- and postinstall scripts are not idempotent yet, but we leave that for later.
