Title: Customizing Linux On Zaurus
Post by: Storm on March 31, 2005, 04:22:41 pm

I was wondering what effects on Zaurus apps that customizing certain aspects of the Linux installation on the Zaurus would have. I know the hostname shouldn't matter, but what about changing the username/UID/GID for the user zaurus? I'm guessing for application purposes, the GID needs to be 0, but do apps use the name or UID for anything?

Thanks,

Until you know a lot about it I would suggest don't.

The important UID/GID other than root (0) is zaurus:qpe or 500:500 respectively.

The permission set over the QtPalmtop directories is set using those UID/GIDs and if you  changed the UID/GID then you will lose access to that.

Also the qpe startup scripts launch Qtopia with the user name zaurus as a parameter.

...there again you might be quite comfortable with a prompt and vi.. apm -s might come in handy  lol.

You cannot change uid for root (0) but you can for zaurus if you know what you are doing and do the appropriate chown to the files afterwards. If you want to change the zaurus username then you will need to hack around and change a few scripts. There isn't much security this would add despite what some security howtos tell you unless you are using NIS on your network

Oh BTW: IPKs are tarballs carrying the installation tree of files.

If there are elements installed for 'user configuration' in an IPK then chances are that they are owned with UID:GID 500:500 (zaurus:qpe).

Okay, cool. So I could change the user zaurus to, say, storm without any ill effects. The reason I would like to do this is a) so ssh works without having to change /etc/ssh/ssh_config on every box I have or typing ssh zaurus@collie every time; and  I want to keep my keys on the Z, including gpg keys, etc.

Thanks,
