To incorporate the updates, you need write access to the distribution directory from a Linux machine, with a working version of rpm installed. There are three steps involved:
If you maintain a mirror of the updates
directory, you can at any time
produce a CD including the current updates by repeating these steps.
During the installation process, some programs are run directly off the CD.
Unfortunately, the FTP program does not always preserve the protection
modes of the files and directories that are copied. Therefore, it is
necessary to make sure that execute permission is given to programs, shell
scripts and shared libraries, before the directory is burned on the
CD. This is done by running the updatePerm
script on your local copy of
the distribution:
#!/bin/bash LIST=/tmp/er3hd3w25 CDDIR=/jaz/redhat-${RHVERSION} # Find all directories, and make sure they have +x permission find $CDDIR -type d -exec chmod -c 755 {} \; # Find all files that are executables, shell or perl scripts find $CDDIR -type f | file -f - | grep -v RPM \ | egrep -i 'executable|perl|bourne|shell' | cut -f1 -d: > $LIST # Find shared libraries find $CDDIR -name \*.so >> $LIST # Make them executable while read file do if [ ! -x $file ] ; then chmod -c 755 $file fi done < $LIST /bin/rm $LIST exit 0
The following script called updateCD
copies all files from the update
directory to the RPMS directory. The script uses some nifty rpm tricks to
determine what packages in the updates directory are more recent. Older
packages are moved to the ${OLD}
directory.
#! /bin/bash # This script updates rpms in a RedHat distribution found in $RPMDIR. # The old rpms will be placed in $OLDDIR. # The new rpms should be located in $UPDDIR. # The architechture is $ARCH. RHVERSION=5.1 ARCH=i386 CDDIR=/jaz/redhat-${RHVERSION} RPMDIR=${CDDIR}/${ARCH}/RedHat/RPMS UPDDIR=${CDDIR}/updates/${ARCH} OLDDIR=${CDDIR}/old if [ ! -d $OLDDIR ] ; then echo making directory $OLDDIR mkdir $OLDDIR fi allow_null_glob_expansion=1 for rpm in ${UPDDIR}/*.rpm ; do NAME=`rpm --queryformat "%{NAME}" -qp $rpm` unset OLDNAME for oldrpm in ${RPMDIR}/${NAME}*.rpm ; do if [ `rpm --queryformat "%{NAME}" -qp $oldrpm` = "$NAME" ]; then OLDNAME=$oldrpm; break fi done if [ -z "$OLDNAME" ]; then echo $NAME is new cp -pv $rpm $RPMDIR else if [ `basename $rpm` != `basename $OLDNAME` ]; then mv $OLDNAME $OLDDIR cp -pv $rpm $RPMDIR fi fi done # Copy new boot image files to the right place... for newfile in ${UPDDIR}/images/* ; do file=${CDDIR}$/${ARCH}/images/$(basename ${newfile}) if [ $newfile -nt $file ] ; then cp -pv $newfile $file fi done exit 0
When installing from the CD, the installation program on the CD
misc/src/install/genhdlist
relies on the file
RedHat/base/hdlist
describing what RPM packages are
available on the CD. This program must be run with the root name of the
distribution as the only argument. Here is the updateHdlist
script:
#!/bin/bash echo generating hdlist... CDDIR=/jaz/redhat-${RHVERSION} ARCH=i386 GENHDDIR=${CDDIR}/${ARCH}/misc/src/install chmod u+x ${GENHDDIR}/genhdlist chmod 644 ${CDDIR}/${ARCH}/RedHat/base/hdlist ${GENHDDIR}/genhdlist ${CDDIR}/${ARCH} exit 0
NOTE: After having incorporated the updates in the main RedHat/RPMS
directory, your copy of the distribution is no longer a mirror of the Red
Hat distribution site. Actually, it is more up-to-date! Therefore, if you
attempt to mirror the distribution, older versions of the RPM's that have
been updated will be downloaded once more, and the updates deleted.
