[Bug 1745664] Re: [regression] systemd-logind crashed with SIGABRT in __libc_connect() from __GI_clnttcp_create() from __GI___libc_rpc_getport() from __GI_pmap_getport() from __GI_clnttcp_create()

[Jonathan]

Apparently a note was added to the systemd NEWS notes, noting this
incompatibility and asking distro maintainers to either override
IPAddressDeny or install ncsd.

https://github.com/systemd/systemd/pull/7343

Note in this pull request someone also mentioned seeing crashes in
systemd-udevd because of this same issue.  It seems like installing ncsd
might be the better solution as it prevents other as of yet undiscovered
services from hitting this new firewall feature of theirs...
