Chris,
I wish I knew all the configuration topics. But just to assure that I can get a stable, usable system up and running, please see the list below. One important aspect is that I do not know everything that can be configured; while reading posts I keep seeing things I have never heard of. But just to get started, here are some exclusive of packages which I would like to cast into this later:
Configuring the System for Another Language
Configuring the Network
Setting the Hostname and Configuring the Name Service
User and Group Databases
Creating Accounts
Shell Environment
Printer Configuration
Configuring the Bootloader
Identifying the Disks
Identifying the Disks Partitions
Configuring LILO
GRUB 2 Configuration
GRUB Legacy Configuration
PyGRUM (any others)
Time Synchronization
Logs
Sharing Access
Thank you,
ray
