Does that also mean that zram will not be fixed in time for the Saucy
release?

I strongly suspect that the the 'sudo parted -l' output of 'Error:

time. I think it was found when people went digging into the issue
with zram freezing.
The good news is that that particular error is not seen in the 3.12rc1
and rc2 kernel that I ran as part of digging into the freeze issue.
I'm not completely sure if ubuntu will be switching to this kernel for
the 14.04 LTS. That is a decision for the kernel team.

It can be disabled just like any other upstart service.
Here is a short documentation link:
http://upstart.ubuntu.com/cookbook/#disabling-a-job-from-automatically-starting
So renaming /etc/init/zram-config.conf to
/etc/init/zram-config.donotstart should work here.
Thanks, Leszek, this was the cleanest work-around. Disabling the
Upstart job means that the zram configurations never run to begin
with.
And it doesn't leave anything dubious dangling (like the 'sudo
parted -l' output of 'Error: /dev/zram1: unrecognised disk label').

Hi Leszek,
John has zRAM in Raring. It was pulled in by a package he
installed, and
I try to help him switch it off.
Probably it is better to do it in /etc/init.d, but I am not familiar
with that method, so I didn't suggest that method. Please
describe it,
I'm reading and learning :-)
Best regards
Nio
