You need the -linuxconf subpackage; but it is deprecated.

Do you mean something like

# vps ax | sed '1d;p' | awk '{print $2}' | sort -u

Kernel does not tell more than EINVAL. Users are very inventively and it
would be very difficultly to say in your example e.g.

Fixed in alpha already; except when the needed change would be trivial,
it will not be fixed in stable.

Looks like a non-production application; 'vserver exec' is for maintenance
tasks only; except the bad environment you will run into problems with
missing /dev/pts entries too.

Already in alpha.

As indicated above, please look into the alpha branch; non-trivial
patches for stable will be probably rejected since this branch is

For details about alpha please see
