Quite agree with you. I have tried dns server setup on Debian and it is so much easier.
How about getting existing DNS server and email server to join the master server if I decided to migrate form master server in Centos 5.5 to Debian? I could not find any instruction nor in the manual.
I could not re-run the isconfig update if I have already completed the installation - for example. (It will give a message nothing to update).
