Minimal installasi debian Lenny menggunakan NetInstall CD, perlu di perhatikan disini hanya menggunakan NetInst CD (atau download sendiri di situs resmi debian.org). Dengan asumsi hanya “Base System” yang minimal terinstall + OpenSSH agar bisa di remote.

Download: Video Installasi

Partisi sesuaikan untuk kebutuhan service server yang nanti akan anda gunakan.
Minimal pisahkan partisi:

/boot 512MB recomended (set readonly reiserfs and boot flags "on")
/ 2GB recomended (reiserfs)
/usr 4GB recomended (reiserfs)
/var 6GB recomended (reiserfs)
swap (2 x ramsize jika ram kurang dari 2GB, 2GB swap => 2GB RAM)
/tmp 512MB recomended (reiserfs)
