[PATCH] zram-config.service should start earlier - add "After=local-fs.target" and "Before=sysinit.target"

[Mantas Kriaučiūnas]

zram-config.service starts too late, because of this using zram for /tmp and other system folder prevents from starting GDM and other services in Ubuntu 18.04

Problem can be solved by adding these lines to /lib/systemd/system/zram-config.service

[Unit]
After=local-fs.target
Before=sysinit.target

[Install]
WantedBy=sysinit.target

I'm attaching a patch for improved zram-config 0.6 by Eugene San, see bug #1548424

Eugene, thanks for including my patch into lp:~eugenesan/+git/zram-config master , but please uncomment this line:

Before=sysinit.target

It's very important to mount /tmp zramfs before sysinit.target, because some script in sysinit creates /tmp/.X11-unix and other important folders and if /tmp is later mount as zramfs then these folders are missing ant this prevents from starting graphical shell (GDM) and some other services in Ubuntu 18.04

Compatibility issue with GDM on Ubuntu 18.04 was fixed in zram-config version 0.7
