Title:
  systemctl daemon-reexec does not update group membership

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  On  Ubuntu 16.04.4 LTS  
  using 
  Package: systemd
  Architecture: amd64
  Version: 229-4ubuntu21.10

  Changes the group membership are not picked up by the systemd process
  for a logged-in user or for a user with enable-linger set regardless
  of login status.  Evidently the

    systemctl --user daemon-reexec

  command preserves group membership across the daemon restart. This is
  bad. It means that only a reboot or

    sudo loginctl terminate-user <user>

  will update the group membership to the proper set. Both of those
  things are extreme disruptions for a system/user that runs servers.

  Can systemctl daemon-reexec be made to update group membership for the
  user in the systemd process?
