Using jail name in rctl(8) doesn't work - jail id works

Hello,

When I specify an rctl(8) rule for a jail using
the jail name it doesn't work. Displaying
resource usage doesn't work either, when
using the jail name, like "rctl -hu jail:myjail"

On the other hand, if I run "rctl -hu jail:3"
where 3 is the jail id, it works as expected.

The manpage examples use the jail name so
it should work. Any idea why it doesn't ? I am
using 9.0-REL on this system.

Should I submit a PR with relevant examples ?

Thanks!

   Check mnt_optnew with vfs_filteropt(9).

   This new option sets the specified ruleset number as the active ruleset
   of the new devfs mount and applies all its rules at mount time. If the
   specified ruleset doesn't exist, a new empty ruleset is created.

   MFC r231267 [1]:
   Add support for mounting devfs inside jails.

Hello,

I submitted the PR which has more information.
jexec(8) is also unable to convert the jail name to jail id on
this sýstem.
My jails are created and started using ezjail, if that matters.

Can you post output of `jls -v` and/or `jls -qn`?

Reason for this is that both rctl(8) and jexec(8) use jail names,
not jail hostnames, and jls(8) called without arguments displays
jail hostname, not jail name.
