QA:Testcase SwapOnZRAM install

Description

Test installation zram-generator only (default disabled)

How to test

1. Recommend removing the following packages. The swap-on-zram implementations in those packages have minor conflicts with zram-generator, but mostly they'll just contribute to user confusion.

   sudo dnf remove anaconda zram

2. Install zram-generator:

   sudo dnf install zram-generator
   

3. Reboot your machine
4. Verify that swap-on-zram is *not* active.

   $ zramctl 
   $ swapon
   NAME       TYPE      SIZE USED PRIO
   /dev/vda1  partition 500M   0B   -2
   

   Everything should look like it usually does, because zram-generator isn't enabled by default.

Expected Results

1. The zram-generator is installed without issues, and is not activated after a reboot.
