[systemd-devel] Query regards to undefine property

[Mohit Agrawal]

Hi Lennart,

  Thank you very much for your reply.After set cgroup property to -1 it is showing value is updated in systemctl output
  systemctl show properties sshd.service -p CPUShares
  CPUShares=18446744073709551615

  but value is not updated in cgroup configuration in below file,
  cat cpu,cpuacct/system.slice/sshd.service/cpu.shares
500

  How we can set the default value in this file without restart systemd daemon or it will be done after implement the "systemctl revert <unit-file>" feature in systemd.

Thanks & Regards
Mohit Agrawal

You can set CPUShares to (uint64_t) -1 to reset it to the
default. Most props have a logic like that.

There's also a TODO list item to add "systemctl revert <unit>" that
will drop all changes made like that back to the defaults in the main
unit file.
