RemoveIPC=yes in Ubuntu 17.10?

A few days ago I upgraded my Ubuntu 17.04 to 17.10 (I think it's something with an aardvark, I am not good at those names). Afterwards I found that my Oracle XE would no longer start. alert_XE.log said things like

    ORA-27300: OS system dependent operation:semctl failed with status: 22
    ORA-27301: OS failure message: Invalid argument
    ORA-27302: failure occurred at: sskgpwrm1
    ORA-27157: OS post/wait facility removed
    ORA-27300: OS system dependent operation:semop failed with status: 43
    ORA-27301: OS failure message: Identifier removed
    ORA-27302: failure occurred at: sskgpwwait1

After some time I found that /etc/systemd/logind.conf had the RemoveIPC line commented out. My backup comprises only the /home partition, so I cannot say what it was before the upgrade. But when I set RemoveIPC=no (the default is “yes”) and rebooted Oracle XE started fine, as it had before the upgrade. So I assume the upgrade somehow made a change to the RemoveIPC setting.

I do not know if this is a bug, a modified feature, or whatever, so I hesitate filing a bug, though the upgrade definitely broke important functionality that had worked before. What do you think?
