I have baught a 1 gig flash drive, I have a dummy harddrive with a 4 gig partition for linux on it. Im doing all of this work on the dummy system, then im going to copy it over to the flash drive once its running properly.
I could use a word of advice on how to do that move if anyone has had a similar experience.

I have installed a copy of suse (without kde/gnome), its starting size is aroung 650 megs.

I need to strip away everything that I dont need, I can figure out most of the programs I can remove because YAST is so simple =).

However the space will soon shrink as I install programs, so I dont expect to have very much space for clutter.

If someone could tell me where to look to remove all build up files that I dont need anymore, such as source code to installed apps, temp files, install packages from updates, and everything else I dont even know about, I would appreciate it. Or a link to such a guide/post would also help.

Thank you for your time.

I'm no authority on the matter and I suppose you already know this stuff, but since I didn't know for ages, you may not.

I keep all downloaded apps and libs in a single place in my harddrive. This enables me to remove what I haven't used or don't need.

I also make sure that I use ./make clean after every source install.

Thats all I can give you, but I'm sure others may see this and help further.
