The /etc/mtree/set.* files are supposed to be useful for verifying the integrity of a system installation, but they often have little mismatches because we don't do anything to automatically verify them.
>How-To-Repeat:
Run `cat /etc/mtree/set.* | mtree -e' in an installed system.
>Fix:
Yes, please!

 Log Message:
 mtree(8): Test the installed sets.

 Except etc and xetc, which likely won't match for reasons that aren't
 great, like etc including empty log files which in an installed
 system have probably changed.

 This test will probably fail, but we should make sure it doesn't!

 Amazingly, only two files are troublesome in these tests, according to
 the i386 testbed:

 https://releng.netbsd.org/b5reports/i386/2024/2024.01.25.19.12.49/test.html=
 #usr.bin_mtree_t_sets_set_base

    check_mtree
    Fail: incorrect exit status: 2, expected: 0
    stdout:
    dev/pts:=20
            permissions (0755, 0555)
    ./var/run/named missing

    stderr:

 I think we can just:

 1. fix the permissions on dev/pts in src/etc/NetBSD.dist.base, since
    it never makes sense for userland to write to files here --
    /dev/pts is always intended to have ptyfs mounted; and

 2. delete var/run/named from src/etc/NetBSD.dist.base, since it gets
    deleted on every boot by rc.d/clearcritlocal (which is presumably
    why it's reported missing here), so anything that relies on
    /var/run/named at boot has to recreate it anyway.


 P.S.  OOPS: mtree lives at /usr/sbin/mtree, so this test should have
       been put at tests/usr.sbin/mtree, not tests/usr.bin/mtree.

 There are, occasionally, some more. Please see PR misc/56896.
 (I must say that I haven't re-checked this recently...)

 Log Message:
 NetBSD.dist.base: Fix permissions on /dev/pts.

 No reason to write to this -- it's expected to have ptyfs mounted,
 and ptyfs doesn't allow changing the directory.  So use 0555
 (-r-xr-xr-x) instead of 0755 (-rwxr-xr-x), like it is by default with
 ptyfs mounted.

 Log Message:
 NetBSD.dist.base: Nix /var/run/named.

 /var/run is emptied at boot time by /etc/rc.d/mountcritlocal, so
 there's no point in creating this at install time -- it has to be
 created on the fly after /var/run is cleared on every boot anyway.

 Mark /var/run/named obsolete in the set lists.  XXX This isn't quite
 right, because it is legitimate for /var/run/named to exist in a
 running installation, but it doesn't exist in a freshly installed
 system any more.  Maybe we should just remove the entry from the set
 lists and add a note to UPDATING about deleting it manually from the
 destdir in incremental builds.

 The new tests do not deal with var_shm_symlink settings in /etc/rc.conf
 (and mtree does not seem to provide a syntax to allow /var/shm to be a
 directory or a symlink to a directory).

 There are also strange link count differences that I do not understand
 and can't seem to be able to get rid of for my local builds and the
 test installs I use them on, e.g. see

 	https://www.NetBSD.org/~martin/aarch64-atf/

 where the only failures (right now) are mtree set list issues.

 Log Message:
 Nix /var/run/named entry from set lists.

 Normally we don't do this, but /var/run/named is

 (a) used by running daemons, so postinstall should not delete it, and
 (b) deleted at boot-time anyway by /etc/rc.d/mountcritlocal, so
 there's no sense in having it checked by mtree.

 However, this means that update builds need manual intervention to
 delete $DESTDIR/var/run/named or else checkflist will fail, so add a
 note to UPDATING about this.

 Do the same with /var/run/lwresd just in case.
