/var/run has moved to /run on most systems and it's use has increased
beyond pid files and sockets. Because of this, new types used in /run
have for some time followed the convention *_runtime_t. This change
would rename all *_var_run_t types to *_runtime_t.
Since this adds many aliases to the policy, the patch set also drops all
old backwards-compatibility aliases.

Any objections to this?

Hello,
I agree with this change.
When I loaded the policy with your patch on my test system, my kernel
logs issued a warning:
SELinux: Context sysadm_u:sysadm_r:samba_net_t became invalid (unmapped).
SELinux: Context sysadm_u:sysadm_r:smbcontrol_t became invalid (unmapped).
SELinux: Context sysadm_u:sysadm_r:winbind_helper_t became invalid (unmapped).
This is because the following optional block from sysadm.te is now dropped:
optional_policy(`
samba_admin(sysadm_t, sysadm_r)
samba_run_smbcontrol(sysadm_t, sysadm_r)
samba_run_smbmount(sysadm_t, sysadm_r)
samba_run_net(sysadm_t, sysadm_r)
samba_run_winbind_helper(sysadm_t, sysadm_r)
')
This block is dropped because it required two types that are not
defined: nmbd_runtime_t and smbd_runtime_t.
In the current refpolicy (git master), there is:
typealias samba_var_run_t alias { nmbd_var_run_t smbd_var_run_t };
Your pull request changes this to:
typealias samba_runtime_t alias { nmbd_var_run_t smbd_var_run_t };
Should nmbd_runtime_t and smbd_runtime_t be changed to samba_runtime_t
in interface samba_admin()?
Other than that, I did not find other issues.
Thanks,
Nicolas

Yes. There was another interface that also had that issue. I updated
the PR to fix it.
