it only came in with fedora33



it seems to add the zram device on top of any existing swap partition,
my fc33 machine still has a ~6 GB LV called swap

# lvs
   LV        VG                    Attr       LSize   Pool Origin Data%
  Meta%  Move Log Cpy%Sync Convert
   home      fedora_localhost-live -wi-ao----  16.93g
   root      fedora_localhost-live -wi-ao----  34.69g
   swap      fedora_localhost-live -wi-ao----   5.87g
   build     raidstore             -wi-ao---- 200.00g
   samba     raidstore             -wi-ao---- 100.00g
   tvheadend raidstore             -wi-ao----   1.00t

# ls -l /dev/mapper/fedora_localhost--live-swap
lrwxrwxrwx. 1 root root 7 Nov 19 09:24
/dev/mapper/fedora_localhost--live-swap -> ../dm-1

But has gained a 4GB zram swap device as well

# swapon --show
NAME       TYPE      SIZE USED PRIO
/dev/dm-1  partition 5.9G   0B   -2
/dev/zram0 partition   4G   0B  100

since it has 32GB, it'll be in trouble of it starts needing either
