Is it possible to have a local cache/ "repository" of all -

1) Updates (Critical, Security, Bug-fixes), and

so that I do not have to download all those again (800 MB + D/L)


Yes,

I have done that for the past 6 months and love it. Basically I have 6-8
boxes that I update from a central computer in my house. Since all of my boxes
don't have the same package config, I created a "Generic" openSuSE repository
for each release (11.0, 11.1) and hold all the common packages there. The
directory structure I use for the repository is:

01:01 nirvana:~/linux/apps> l /home/backup/rpms/
total 32
drwxr-xr-x 8 david dcr 4096 2009-08-10 21:39 ./
drwxr-xr-x 28 david dcr 4096 2009-07-27 17:47 ../
drwxr-xr-x 6 david dcr 4096 2009-08-20 18:58 data/

drwxr-xr-x 12 david dcr 4096 2009-08-20 18:58 openSUSE_11.0/
drwxr-xr-x 8 david dcr 4096 2009-04-07 19:05 openSUSE_11.1/
drwxr-xr-x 2 david dcr 4096 2009-04-08 00:33 openSUSE_11.2/

Where you have the normal architecture divisions you would expect under 11.0,
11.1, etc. Like:

01:01 nirvana:~/linux/apps> l /home/backup/rpms/openSUSE_11.0
total 776
drwxr-xr-x 12 david dcr 4096 2009-08-20 18:58 ./
drwxr-xr-x 8 david dcr 4096 2009-08-10 21:39 ../
drwxr-xr-x 2 david dcr 4096 2009-08-07 14:14 compiz-new/
drwxr-xr-x 2 david dcr 77824 2009-08-09 04:02 delta/
drwxr-xr-x 2 david dcr 4096 2009-07-13 11:23 i386/
drwxr-xr-x 2 david skyline 155648 2009-08-19 18:56 i586/
drwxr-xr-x 2 david dcr 12288 2009-08-15 23:07 i686/
drwxr-xr-x 2 david dcr 69632 2009-08-20 18:58 noarch/
drwxr-xr-x 4 david dcr 12288 2009-07-27 16:44 openOffice/
drwxr-xr-x 2 root root 4096 2009-08-20 18:58 repodata/
drwxr-xr-x 2 david dcr 4096 2009-08-08 02:01 src/
drwxr-xr-x 2 david skyline 425984 2009-08-20 18:58 x86_64/

The additional compiz-new and openOffice directories above just hold the
alternate version for each like I have compiz 7.8 in my repository, but have
8.2 avaiable. For openOffice, I have 2.4 in the repo and 3.0.1 in the extra
openOffice directory.

The key to making this work is to have all clients that do updates use a
script to separate all the files by architecture and then upload to the server
via rsync. That way the next box that gets updated, pulls the rpms from your
server instead of from the internet.

By doing it this way, you have one central repository, that manages
duplicates, and that holds updated packages for rpms of all architectures.
Further, I put the repository under /home so it gets the space off the /
partition freeing up space there.

The first thing you want to do is to is to set the "keeppackages" option for
each of your repository definition definition files in /etc/zypp/repo.d/ and
turn off the use of delta.rpms in your zypper.conf file. They may be smaller,
but they are a hell of a lot slower to install.

I have just a couple of scripts that do the management of the repo. The
client-side and server-side scripts I use can be obtained at:

http://www.3111skyline.com/download/openSUSE/pkgmanage/

After one of your computers has done an update, just run the zyppmerge.dev
script on the client and it will gather all the newnly downloaded rpms and
rsync them to the box you have chosen as the server (you just need to edit a
few variables to set the appropriate hostname, etc. This client side script
will then call the server-side script that will eliminate any duplicate
packages, update the deltarpm file and create and sign the repository with the
new files in it to update the repo before passing control back to the client.

Give it a go and see if it meets you needs.
