[Feature request] /etc/init/zram-config.conf has no any options. Please add a few.

Such people as me would like to set some permanent paramenters for zram without editing /usr/bin/init-zram-swapping script file. I think it's wrong to edit something in /usr/bin.

Status changed to 'Confirmed' because the bug affects multiple users.

I presume this is referring to the hardcoded calculations
for NRDEVICES and the critical calculation using it:

   mem=$(((totalmem / 2 / ${NRDEVICES}) * 1024))

(There are a few others that perhaps should be more easily
adjusted.) Yes, this also has annoyed me, albeit, to-date,
the hardcoded values seem to be Ok for me on my system.

I'd also like to be able to specify more zram devices;
i.e., have some which are not used for swap. Currently
(without testing) all those created are used for swap,
and it's not possible to create additional devices (but
I suppose one could then swapoff(1) one or more to get
the desired "extra" device(s)?).

Starting with Disco Dingo (19.04) there is a new package `zram-tools'
which is roughly configurable as per many of the above wishes.

   https://launchpad.net/ubuntu/+source/zram-tools

From eyeballing it, it seems like it should work on earlier releases
(but see caveats below); however, I have not tried.

Some caveats:

1. Have at most one of `zram-config' or `zram-tools' (NOT both) installed.

2. The `zram-tools' defaults are slightly different from `zram-config'.

3. The version of `zram-tools' currently proposed for Eoan E<something> (19.10?)
   has some simple fixes and perhaps should be preferred?

I am currently using 19.04's 0.3.2-1 with Disco Dingo but will probably
switch to using 19.10's (Eoan's) 0.3.2-1-1 on that system to pick up the
above-mentioned configuration fixes.
