Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.

Implement a new init(8) option in /etc/ttys. If this option is present
on the entry in /etc/ttys, the entry will be active if and only if it
exists. If the name starts with a '/', it will be considered an
absolute path. If not, it will be a path relative to /dev.
This allows one to turn off video console getty that aren't present
(while running a getty on them even when they aren't the system
console). Likewise with serial ports.
It differs from onifconsole in only requiring the device exist rather
than it be listed as one of the system consoles.

There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed. It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).
Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname. If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname. Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.
Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line
by default without providing one on all systems by default.

I've noticed various terminal emulators that need to obtain a sane
default termios structure use very complex `hacks'. Even though POSIX
doesn't provide any functionality for this, extend our termios API with
cfmakesane(3), which is similar to the commonly supported cfmakeraw(3),
except that it fills the termios structure with sane defaults.
Change all code in our base system to use this function, instead of
depending on <sys/ttydefaults.h> to provide TTYDEF_*.
The ttyslot() function was originally part for SUSv1, marked LEGACY in
SUSv2 and removed later on. This function only makes sense when using
utmp(5), because it was used to determine the offset of the record for
the controlling TTY. It makes little sense to keep it here, because the
new utmpx file format doesn't index based on TTY slots.
Just like bin/ and sbin/, I think setting WARNS to the highest value
possible will make it more attractive for people to fix warnings.
- The WARNS variable is set in the Makefile in the directory of the
application itself, making it more likely that it will be removed out
of curiosity to see what happens.
- New applications will most likely build with WARNS=6 out of the box,
because the author would more likely fix the warnings during
development than lower WARNS.
Unfortunately almost all apps in libexec require a lowered value of
WARNS.
