Is anybody familiar with how to go about frugal installations of different linux distributions? The information I have is mostly from a poster on linuxquestions.org (here's the thread), and installation worked for me on one particular distribution.
But I haven't been able to find any general information on how this method of installation works, and how to apply it to other linux distributions. I'm also clueless about the relative advantages and disadvantages of this over other methods.
The method will obviously differ based on the distribution. Some distros have easily selectable minimal installations (like the amazing new http://susestudio.com/), while others, like Red Hat Enterprise (CentOS/Scientific) need custom kickstart files files created to craft the installation to your exact specifications.
That assume that you know what the exact specifications are, though. I'm a huge fan of System Management by the Least Bit Principle. It's a good policy, and determining what that least bit is becomes difficult.
Design your server to have a purpose, and ensure that the only software and libraries installed directly support that purpose. Ensure that you've got configuration management in place (like Puppet or cfengine) to make changes in the future.
You already have a DLS reference.
And with TinyCore too.
Could get some more references at DistroWatch (maybe by category).
USB Installations of Ubuntu are quite small and pretty quick to boot.
What is your target exactly?
What are you trying to do? Do you have a small computer on which to install? Are you trying to achieve a particular purpose?
Most popular distributions are pretty large on average, but you can get them to run in smaller configs (like Xubuntu on instead of Ubuntu cuts back a little...I've heard people running it on systems with 128 meg of memory without much problem).
Otherwise you could install something really small like DSL (Damn Small Linux). But none of this really helps without knowing what you're trying to achieve.
Debian's base installation is < 250MB, installing straight off the CD.
