Tiny and I think they are all obvious.

init: rename *_pid_* interfaces to use "runtime" 
The name of these interfaces is clearer that way.

This comes from a suggestion from
https://lore.kernel.org/selinux-refpolicy/dedf3ce8-4e9f-2313-6799-bbc9dc3a8124@ieee.org/

Label service binaries in /usr/bin like /usr/sbin 
For some services, the program responsible for the service has a file
context which is defined only when it is installed in /usr/sbin. This
does not work on Arch Linux, where every program is in /usr/bin
(/usr/sbin is a symlink to /usr/bin).

Add relevant file contexts for /usr/bin/$PROG when /usr/sbin/$PROG
exists.

Sugar, David 82494cedc1 pam_faillock creates files in /run/faillock 
These are changes needed when pam_fallock creates files in /run/faillock
(which is labeled faillog_t).  sudo and xdm (and probably other domains)
will create files in this directory for successful and failed login
attempts.

systemd: allow systemd-logind to use getutxent() 
systemd-logind reads /run/utmp in order to warn users who are currently
logged in about an imminent shutdown. It calls utmp_wall() in
https://github.com/systemd/systemd/blob/v240/src/login/logind-utmp.c#L75-L87
This function calls glibc's getutxent() here:
https://github.com/systemd/systemd/blob/v240/src/shared/utmp-wtmp.c#L401
This function, implemented in
https://sourceware.org/git/?p=glibc.git;a=blob;f=login/utmp_file.c;h=040a5057116bb69d9dfb1ca46f025277a6e20291;hb=3c03baca37fdcb52c3881e653ca392bba7a99c2b
, opens and locks /run/utmp in order to enumerate the users.

selinuxutil: allow restorecond to try counting the number of files in cgroup fs 
When restorecond calls selinux_restorecon(), libselinux scans
/proc/mounts in a function named exclude_non_seclabel_mounts with the
following comment
(https://github.com/SELinuxProject/selinux/blob/libselinux-2.8/libselinux/src/selinux_restorecon.c#L224-L230):

    /*
     * This is called once when selinux_restorecon() is first called.
     * Searches /proc/mounts for all file systems that do not support extended
     * attributes and adds them to the exclude directory table.  File systems
     * that support security labels have the seclabel option, return
     * approximate total file count.
     */

The "approximate total file count" is computed using statvfs(), which
results in a system call to statfs().

The cgroup filesystem supports security label (/proc/mounts shows
"seclabel") so restorecond uses statfs to try counting the number of its
inodes. This result in the following denial:
