Documentation Beats Installer

Beat is open
This beat is now ready to have Fedora 25 content added by the beat writer

Notes:

• Low memory installations work better using methods where squashfs.img doesn't need to be kept in memory, ie nfs,live image.
• Document changes in Kickstart syntax
• Apparently Anaconda now supports swap on zRAM - ask vpodzime

 zRAM swap for Anaconda: zram can be turned on and off with the inst.zram argument. It will be used 
   automatically for systems with <2GB, and not used for systems with >2GB.
   
   zRAM is a standard block device like tmpfs with one nice difference -- its
   content is compressed. One clever usage of such device is using it as a swap
   device which effectively means one can have compressed RAM. Some experiments
   show that by using zRAM as a swap device in the installation process anaconda
   can install to machines with lower amount of RAM (succeeded with 320 MB) and
   installations on low-RAM systems (< 1 GB) run faster due to usage of zRAM swap
   instead/together with the standard swap we create and use for package
   installation.
   
   Specific limits, numbers and way of implementation may be changed in the future,
   but this commit introduces the basic idea and straightforward approach.
