How to install the slackware linux on the smallest harddisk space
 

Hi all,
Have any of you tried to install the slackware on the smallest hard-disk space?
This is the idea... I wanna use slackware as a network router/bridge.
I dont want any GUI, I dont want any unecessary process.
I just want it to work as a bridge/router which utilise small harddisk.
If possible please let me know step by step and which packages need to be removed.
Any reply would be very appreciated. Thank you

If you want smaller than 20MB you have to do some fairly drastic stuff that may affect usability.

that's very good stuff,
my other question: how to install it on the pure linux partition?

You need to have it running or some linux running in order to migrate ot to a linux partition. Since that's built on an older version you might rather just use the list and do a reglar install using those packages.
But, look at this:

for a more reasonable starting point.
You could also just follow the installed package list for ZipSlack. There also is RUNT linux -ZipSlack plus even more networking tools.
