Differences between FreeBSD and Fedora installation
1. FreeBSD must be installed into a primary partition and doesn't support the operation to the logical partition.
2. FreeBSD uses the concept of Slice and Fedora uses partition.
3. FreeBSD uses one of the slice of a disk as SWAP and Fedora uses individual partition as SWAP. 
4. FreeBSD supports UFS file system and Fedora supports EXT2, EXT3, and so on.
5. FreeBSD uses text-based sysinstall utility to install OS and Fedora uses graphic mode.
6. FreeBSD uses tcsh as default shell and Fedora uses bash.
7. GUI may not be installed on FreeBSD.
Pros of FreeBSD installation process

  /etc/fstab       --contains file systems
  /etc/ftpusers    --list of users disallowed any ftp access
  /etc/group       --contains the group of the system
  /etc/hosts       --the hostname and their IP address that can be recognized by the local machine
  /etc/inetd.conf  --internet server configuration database
  /etc/netconfig   --the network configuration file
  /etc/netstart    --start network for user convenience
  /etc/passwd      --contains the users of the system

Setting up a network 
In the file /etc/rc.conf, we can configure the network card.
Start-up scripts in FreeBSD 
In FreeBSD, the start-up scripts is in the /etc/rc.d directory. If you want to make them enable, you should set them in the /etc/rc.conf file.
