Thanks for RAM SWAP improvements, Eugene :)

Now zram-config is even more useful for devices with SSD/Flash storage - until Eugene improved zram-config I've used tmpfs for /tmp in computers with SSD/Flash storage, but zram is better for /tmp, right? ;)

P.S. I copied zram-config 0.6 from ppa:eugenesan/ppa to main Baltix GNU/Linux repository - ppa:baltix-members/ppa , look at

Dear Ubuntu developers, zram-config was greatly improved by "Eugene San" 2 years ago (2016-02-22), what could I do to see these improvements in Ubuntu 18.04 (Bionic) LTS ?

Dear Eugene San, could you fix important bug in your zram-config branch lp:~eugenesan/+junk/zram-config ?

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

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



I'm attaching a patch for zram-config 0.6

See bug #1761740 for more info.
