Finally, I have reinstall my home ipmasq box to debian Sarge. (It is a Mandrake previously, while once a upon of time I want to try Mandrake 7.x for teaching and haven't time to upgrade it for years) Alas that it is a pretty old box (AMD K6, bought in 1999) and I haven't touch it physically for long time, the CD-ROM drive is dirty and fail to boot any Debian Installer within my finger except the BBC Linux 2.1. Therefore, I decided to install the sarge via debootstrap. It is interest and great. May be I would write some article about it later. Beside, I found galternatives enter Sid yesterday, it's also the time for me to write something about update-alternatives.
