[A new addition to this HOWTO - not yet complete]
So you've installed your system, or you want to install X but you don't have enough room on your disks to install it. What can you do to free up some space? There is a huge amount of space that can be freed up by deleting the unused material in a dpkg-based system.
Many libraries and binaries are distributed with debugging information. Running
file on these files will tell you ``not stripped'' if so. When copying binaries
to your root filesystem, it is good practice to use:
objcopy --strip-all FROM TO
objcopy is a binary found in the binutils package.
Important: When copying libraries, be sure to use strip-debug instead of strip-all.
These include changelog's, todo list's, readme's, etc., but be careful what you delete.
You are stuck with the psion keyboard, and don't mess with it.
