If you use a fedora based os and experience a slow boot this is for you. It seems to stem from the zram start job at boot.
First type dnf list installed | grep zram in a terminal.
The output should show 2 packages (zram-generator and zram-generator-defaults)
Simply remove (both get removed if either is removed) with sudo dnf remove zram-generator
This should work for any fedora based distro experiencing abnormally slow boot times.
