For my system I have some specifications:
1.- Debian tools (dselect, apt ...) must be available inside the system, so I
don't need a special way to update the system, just Debian
2.- It must be able to install a wide range of apps
3.- It must be small
If I want to use current Sid I have a problem: packages data files.
/var/lib/dpkg/available : 16Mb
/var/lib/dpkg/available-old : 16Mb
/var/cache/apt/*.bin : 13 Mb
/var/lib/apt/list/* : 17 Mb
/var/lib/status : 1.7Mb
/var/lib/status-old : 1.7Mb
This is a loooooot of space. More than the space I'm using for real
I can just delete all that files (except status files) and save the space or
maybe there's a better approach.
I've also thought of doing my own private and small Debian repository mirror.
Too much traffic for my small server.
