[Libtirpc-devel] [RFC][PATCH rpcbind 3/4] systemd/rpcbind.service.in: Add various hardenings options

[Petr V. <pv...@su...>]

We've been running rpcbind 1.2.6 with it in openSUSE since 2021.

NOTE: In systemd < 244 (released Nov 2019) some of these options are
unknown and will produce warnings, see

https://en.opensuse.org/openSUSE:Security_Features#Systemd_hardening_effort
