Re: does numeric only name of jails not allowed (bug?)

Hello Vadim,

Unfortunetly it does not work:

root@builderhost:/ws/a7777 # jail -c 47777
jail: 47777: host.hostname: variable "name" not found
jail: 47777: exec.consolelog: variable "name" not found

root@builderhost:/ws/a7777 # head embedding/jail-a7777.conf
...
"47777" {
        host.hostname = "${name}";
...
