Thanks, please update the bugs when you have done so.

Ubuntu 18.10 is in feature freeze mode since Aug 23rd (see
https://wiki.ubuntu.com/CosmicCuttlefish/ReleaseSchedule), and I can't
update the ndctl version there without a justification in the form of
a Feature Freeze Exception
(https://wiki.ubuntu.com/FreezeExceptionProcess). Furhtermore, that
ndctl v62 update has a new daemon which fails to start if the hardware
isn't available, and that fails the package installation, which is
something we cannot have. I will need to find ways to handle this in a
more graceful manner.

That being said, are there important bug fixes that exist in ndctl v62
that make v61.2 unsuitable for release in both Ubuntu 18.10 and Ubuntu
18.04?

Thanks
