Editing Basic Fedora 31+ Installation

== Fedora Distribution Install ==
Fedora 31 KDE Workstation install from DVD install disk
During install process:
* use custom formatting
* set partition type to 'standard'
* click on 'automatically create partitions
* delete /home partition and increase size of / to fill the disk
* set hostname (if known) 
* enable all basic network interfaces (do not rename -- it will crash the installer)

== Basic system prep ==
Many of these packages are already installed, but they are needed later, so we just make sure ...
 yum -y install net-tools rsync zsh yum-utils mlocate drpm
 yum -y install sshfs nfs-utils 
 yum -y remove firewalld postfix
 yum autoremove -y NetworkManager NetworkManager-libnm # only if not using as graphic workstation
 yum -y update

Disable SELinux (no comment)
 sed -i 's/=enforcing/=disabled/g' /etc/selinux/config
 setenforce 0

Reboot and verify everything comes up properly
 reboot

== System Configuration ==
Set the system hostname (if not set during installation)
 hostnamectl set-hostname <hostname>.williams.localnet

Enable passwordless sudo:
* use visudo
* search for 'wheel'
* comment out that line
* uncomment the one below it

Set '''zsh''' as the default shell
* chsh to /bin/zsh (both root and ewilliam)
* copy '''ssh''' and '''zsh''' config files (both root and ewilliam)
  scp -r calormen:.ssh .
  scp calormen:.zshrc .
  scp calormen:.zlogin .

Enable the SSH server (why it's not enabled by default is strange ...)
 systemctl enable --now sshd

Enable automatic updates.  Parameters can be set in the config files '/etc/dnf/automatic.conf'
 yum -y install dnf-automatic
 systemctl enable --now dnf-automatic.timer

Setup backup to central file server
* copy scripts from calormen
 scp calormen:/etc/cron.daily/backup /etc/cron.daily
 scp calormen:/usr/local/bin/rsync_backup.sh /usr/local/bin/
* edit rsync_backup.sh, changing target directory and list of directories to backup
* create target directory on storage1 if it doesn't exist
* run /etc/cron.daily/backup to verify proper operation

Enable connection to the central log server scp aslan:/etc/hosts /etc/hosts

 scp calormen:/etc/rsyslog.d/99-remotelog.conf /etc/rsyslog.d ; systemctl restart rsyslog

Enable mail to central mail server; SSMTP package is not yet in the CentOS 8 epel repo, so we need to 'borrow' it from CentOS 7
 # download ssmtp RPM from somewhere
 wget http://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/s/ssmtp-2.64-14.el7.x86_64.rpm
 yum -y install ssmtp-2.64-14.el7.x86_64.rpm
 echo "root: ewilliam@williams.localnet" >> /etc/aliases
 echo "ewilliam: ewilliam@williams.localnet" >> /etc/aliases

enable references to non-williamsnet addresses for development cluster
 scp aslan:/etc/hosts /etc/hosts
