To use zram-init, activate it in your kernel and add it to the default
runlevel:
	rc-update add zram-init default
If you use systemd enable zram_swap, zram_tmp, and/or zram_var_tmp with
systemctl. You might need to modify the following file depending on the number
of devices that you want to create:
	/etc/modprobe.d/zram.conf.
If you use the \$TMPDIR as zram device with OpenRC, you should add zram-init to
the boot runlevel:
	rc-update add zram-init boot
Still for the same case, you should add in the OpenRC configuration file for
the services using \$TMPDIR the following line:
	rc_need=\"zram-init\""
