Adding The Speed Up Pm Hack To Suseconfig

OK, so you copy this script;

#!/bin/sh
sqlite3 /var/cache/zypp/zypp.db vacuum
rpm --rebuilddb******** # takes long
for fn in****** /var/cache/zypp/zypp.db \
****************/var/lib/rpm/Packages** \
****************/var/lib/rpm/Filemd5s** \
****************/var/lib/rpm/Dirnames** \
****************/var/lib/rpm/Basenames
do
********cp $fn $fn.new || exit 1
********rm $fn
********mv $fn.new $fn
done

Script came from http://en.opensuse.org/SDB:Speed_up_..._Manager_Stack

Once this is done, if you want it to run with SuSEconfig, simply move the script to /sbin/conf.d/

Now, if you leave the script as is, it will run every single time SuSEconfig is invoked. If you don't want this, but still want it run run with SuSEconfig, you can add a counter to the above script, so that say, after 50 SuSEconfig runs, the script would run.

Here is a link on bash programming to give you some examples on counters; http://www.faqs.org/docs/Linux-HOWTO/Bash-...ntro-HOWTO.html

So, ok, I asked yaloki about the counter since I am new to bash scripting. Yaloki came up with this;

#!/bin/bash

# default value if not defined in /etc/sysconfig/zyppdefrag:
ZYPP_DEFRAG_EVERY=5

# read config but don't fail if the file doesn't exist
. /etc/sysconfig/zyppdefrag &>/dev/null

count=$(cat /var/adm/SuSEconfig/zyppdefrag-count 2>/dev/null || echo 0)
count=$(( $count + 1 ))
echo $count > /var/adm/SuSEconfig/zyppdefrag-count

[ "$count" -lt 10 ] && exit 0

sqlite3 /var/cache/zypp/zypp.db vacuum
rpm --rebuilddb******** # takes long
for fn in****** /var/cache/zypp/zypp.db \
****************/var/lib/rpm/Packages** \
****************/var/lib/rpm/Filemd5s** \
****************/var/lib/rpm/Dirnames** \
****************/var/lib/rpm/Basenames
do
********/bin/cp "$fn" "$fn.new" || exit 1
********/bin/rm "$fn"
********/bin/mv "$fn.new" "$fn"
done

echo 0 > /var/adm/SuSEconfig/zyppdefrag-count

Yaloki also wrote this, so that it is configurable in YaST.

## Path:********** System/Zypp/Defragmentation
## Description:****defragment the RPM and zypp databases
## Type:********** integer
## Default:********"5"
#
# After how many runs of SuSEconfig should the RPM
# and zypp databases be defragemented ?
#
ZYPP_DEFRAG_EVERY="5"

Make sure to place this one in /etc/sysconfig/zyppdefrag (which you may have to create)

And here is a picture.

Now, if you do a lot of installing/upgrading or removing packages (like I do) then maybe an interval of 5 is ok, otherwise change the number to a higher value. If all you do is the security updates, setting the value to 50 might be more appropriate.
