elaborate on CPUD(as remote):9p mount no such device about cpu

[orangecms]

This was likely due to the vendor kernel not supporting 9p.
I'll recheck and see what the current behavior is, rewrite to a more elaborate error message with a hint or something.

yeah, one option is to have it print out the right config values to add to the kernel?

Leaving this here as an FYI:
I was facing the same issue and the comment from @orangecms put me on the right path to working around this. I was trying to run cpud on AmazonLinux and failing. Tried with Ubuntu and it worked just fine.

Hi, I have encountered a similar problem. I am trying to run cpud on a machine with a custom distro.
On the remote I run:

cpud -pk /home/root/.ssh/key.pub

An on the host:

./cpu -key $KEY -namespace=/home 192.168.4.189 /bin/date
CPUD:Namespace: 9p mount no such device

If this is a kernel config issue, does anybody know how to enable support for 9p?
