need HELP /* upgrading */

[jack <ifup@yifan.net>]

hi,

I am trying to upgrade the slink to potato.  Got some questions:

1. glibc2.1 is required for most recent applications.  The version of it
in slink, i believe, is something 2.0.xx.  So which package should I
upgrade first?

2. How to search a package by name?  either in installed list or on ftp
site?  I am using dselect.

3. how to uninstall mozilla?  It just does not work for me.

4. how to make a bootable cdrom for potato (unstable release)?  If it can
be done, I am going to give it a fresh install instead of upgrading.  I
know, upgrading is pain in the ***.  I've already have 200M main/binary
What else do I need?  If possible, I'd like to use wget.....

thanks,

jack
