From: Russell Coker @ 2021-10-09 9:59 UTC (permalink / raw)
To: selinux-refpolicy
Allow systemd_nspawn_t to remount sysfs and stat cgroup.
Allow it to mounton the kernel symbol table and use systemd_nspawn_runtime_t
for named pipes.
Allow systemd_passwd_agent_t the sys_resource capability and access to sysfs.
Allow systemd_user_runtime_dir_t to delete user tmp dirs and named pipes.
Allow udevadm_t to stat cgroups and tmpfs.
Make certbot run in it's own domain from unconfined_t.
Added mounton_dir_perms and mounton_file_perms macros.
Change corenet_tcp_connect_generic_port to allow connecting to
unreserved_port_t as well as port_t.

I'm a bit dubious on this, but if we make this change, it should be reflected in

I think I'm ok with the rule changes otherwise; however, I'll wait on this due
to the mounton questions in your other patch.
