What should I do about it? Is that a serious issue to take care of?
Edit: I use the latest LTS kernel release.
2#Edit: I realized that I had upgraded the kernel yesterday, though I always do reboot after updating critical packages on my system so I believe the error wasn't caused by the kernel update. I'm not sure though.

[2017-10-09 19:22] [ALPM-SCRIPTLET] >>> Updating module dependencies. Please wait ...
[2017-10-09 19:23] [ALPM] upgraded linux-lts-headers (4.9.53-1 -> 4.9.54-1)3#Edit: That could be related to the issue: https://github.com/systemd/systemd/pull/6294
A new mount option, "nsdelegate", was added to cgroup v2 to address this issue. The flag is meangingful only when mounting cgroup v2 in the init namespace and makes a cgroup namespace a delegation boundary. The kernel feature is pending for v4.13.
looks good, but let's wait for the v235 cycle for this

I have the same journal entry:
kernel: cgroup: cgroup2: unknown option "nsdelegate"However, I am still on kernel 4.12 (I can't update to 4.13 because of a wifi issue).
I assume from reading the linked systemd issue (from your #3 edit) that we'll see this log entry whenever using systemd 235 while kernel < 4.13. If you're on LTS you're not on 4.13.
I'm going to ignore it because it looks like it falls back if not supported:
this commit makes systemd try "nsdelegate" first when trying to mount cgroup v2 and fall back if the option is not supported

Thanks for sharing! By the way, I did a little more research on my own, and it turns out that the Systemd warnings in the dmesg output as seen in my first post concern another features that were brought to Systemd 235 that aren't supported by the LTS kernel yet.

The three options are thin wrappers around kernel functionality introduced with Linux 4.11: the control group eBPF hooks.
It looks like it's all going to be gone once LTS 4.14 kernel is released.
In that case, I'm going to mark the topic as solved as there's nothing to complain about further.
