Currernt config hook implementation scales very badly

[XiaoGuo Liu]

Hi Ciao,

Thanks! I just upgraded it to edge channel, and now it works as expected.

liu-xiao-guo at localhost:~$ snap set core service.ssh.disable=true
liu-xiao-guo at localhost:~$  sudo snap set core service.ssh.disable=true
liu-xiao-guo at localhost:~$  snap set core service.ssh.disable=true
liu-xiao-guo at localhost:~$ snap set core service.ssh.disable=false
liu-xiao-guo at localhost:~$ snap interfaces |grep core
:core-support             core

I think the problem could be that the stable channel does not support it.

Best regards,
XiaoGuo
