If zram is not module init-zram-swapping exit 1.

[silviop]

/usr/bin/init-zram-swapping check against existance of zram module,
 but on embedded system zram may be statically compiled in kernel so it fails and exit 1.

I suggest to add more robust check for zram availability in the system.

Workaround :

Remove all before modprobe and set ${NRDEVICES} to number of existent /dev/zramX devices.

I've found improved version of zram-config at lp:~eugenesan/+junk/zram-config with following improvements:

 Utilize zram built-in multi-threading, config file and /tmp mounting
   * Rework scripts to Utilize built-in zram multi cpu support
   * Add support for /tmp mounting on zram device
   * Introduce defaults file for setting parameters
   * Rename scripts and install them to /sbin

See LP bug #1548424 for more info.

Maybe you can ask Eugenesan to improve checking for zram availability in the system ?
