===Verify===
 
The observations below are made from anaconda git logs, and should be verified against the actual version of Anaconda shipped for F21
 
 
* Low memory installations work better using methods where squashfs.img doesn't need to be kept in memory, ie nfs,live image.
 
 
*  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.
