* 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
Specific limits, numbers and way of implementation may be changed in the future,
but this commit introduces the basic idea and straightforward approach.
* geolocation for initial tz, lang configuration
* use the experimental `dnf` backend instead of yum with the "dnf" command line argument
