I guess we would have to verify that

You still haven't explained why zfs

As I tried to explain, the risks of collisions without central
coordination

Absolutely, yes. I found this out because, for some reason that I don't
know, libvirtd wants a unique identifier. It defaults to

I agree. It's the most likely outcome if this issue was reported to
glibc upstream.

Other platforms have deprecated gethostid, that's the best way forward for

Which platforms is this? I find FreeBSD recommend to use sysctl and

Which platforms is this? I find FreeBSD recommend to use sysctl and
KERN_HOSTID to get the hostid integer directly from the kernel instead
of using gethostid(), which isn't really

Ah, thank you very much for bringing this systemd setting to my
attention. I was not aware of it.
I agree that it seem very similar in purpose and implementation. Will
it be available on non-linux Debian architectures

Reassigning to glibc as that is the source of gethostid() where the
problem with the missing unique identifier originates. Using the
