Installation Source creation status

June 6th, 2008 by

There is some work going on to put installation source creation functionality into kiwi.
At the moment kiwi can use prepared installation sources such as:

  • BuildService Repositories
  • mounted DVDs
  • FTP trees

But what if you have a local Build Service building some binary only packages and you wish tp make a installable media set from, say, “SLES + binary only drivers”?
You can use the inter-BS-Connectivity feature to only build the drivers (and not the whole distribution) in your BS and then create an installation source from your main BS project.

This is possible since release of the package kiwi-instsource which extends the functionality of the config.xmlfile to allow the compilation of an installation source from scratch.
Hereby “scratch” means directories containing .rpm and .spm files. Of course some information must be provided for the metadata creation — but this is also all in the config file (with one known exception — the PDB data).

The rest is figuring out which packages must be on the installation source.
Since it is perfectly ok to have conflicting packages in instsources, there is no dependency check or package resolving in this stage. The information must come from the user.

Therefore the package list may become rather long and I already plan to implement some simplification.
These plans include:

  • allowing more than one <repopackages> section
  • implement outsourcing blocks in separate files using XML functionality

Find Your Monitor

June 6th, 2008 by

Quite often I get bugreports that the hardware detection doesn’t find the monitor. Well, what should I do? We run a Video BIOS function for it, and if the BIOS can’t see the monitor, we’re out of luck.

But maybe not? It can well be that running BIOS code in Linux is not the best idea either.

To shed some light I wrote a small (6.5k if you must know) DOS-program and put it on a bootable CD. If that can’t detect the monitor it’s probably the BIOS’s fault, if it works blame, well, someone else. 😉

On a side note, the program was created with the usual gcc. It’s really surprising what you can do with a nice include file and a linker script.
