more fallout from removal of lint

[Don Lewis]

Since lint was removed from 12.0-CURRENT, it is not possible to build
11.1-STABLE on a 12.0-CURRENT host, but I was able to work around that
by copying /usr/bin/true to /usr/bin/lint. Unfortunately, that trick
doesn't work when updating a 11.1-STABLE poudriere jail on a
12.0-CURRENT host.

I had filed[1] a bug report about this a little over a month ago and
FreeBSD was disinterested in even discussing it. HardenedBSD worked
around the issue by disabling the build of lint in its 11-STABLE and
10-STABLE trees.

Thanks,

I ran also into this problem and for security reasons, I HAVE TO update several
hosts to 11.1-RELENG-p6. I can not, because the building host (poudriere, also
the binary packages for a binary update of base) is on CURRENT.

I hope this issue gets fixed soon.

Oliver

There is a big difference between what is "possible" and what is
"supported".
Since CURRENT is branched off of STABLE, there is always a period of time
where the two build systems are compatible. During this time, it is
*possible*
to build STABLE on a CURRENT host.

However, the build system for CURRENT can be changed in
ways that make it incompatible with building STABLE. This is normal and
expected behavior for a development branch. It has never been a *supported*
option to mix and match source code from different branches on a single
host.

Can you try creating a 11.1-STABLE jail on your 12-CURRENT host, and
perform the build within the jail? I'm not clear on what role Poudriere
plays
in all of this, so that may take some additional work to straighten out.

Regards,

- Mark

If I understand right, at the transition from
stable/11 to release/12.0 and stable/12,
stable/11 is supposed to be able to build 12
as part of a source based upgrade. (Normally
the most recent release/11.? should be able
to as well? The oldest supported release/11.?
as well?)

So at certain times one direction of mixing
seems to be supported for specific versions
in order to allow progressing forward.

That does not mean that the other direction
is supported.

It does seem to me that having a head/ based
system set up to do the stable/?? builds is
backwards generally under the normal principles
of operation. The other direction seems to be
the general intent.

Even having stable/11 try to build, say,
stable/10 would seem to be backwards on
the general principles if I've understood
right. head/ is not actually essential to
the issue.

The original material below was tied to
buildworld buildkernel activity of itself.

This is somewhat different than having
COMPAT_FREEBSD*'s in the live kernel and
running an already correctly built, older
world in a jail based on such a newer
kernel and world.

That does not mean that the other direction
is supported.

This can have implications for poudriere,
needing to use "pre-built distribution
options" instead of "build from source
options". There would be source around
that "will not be built from" but for
which the source tree is used in the
jail, at least to build ports that
contain modules. (This is another
case of having sources from multiple
branches on a single host. But
the usage is not for buildworld
buildkernel in this context.)

For custom configurations, one might
have to use, say, stable/11/ to build
a world that is then to be put in a
head/ context for use in poudriere.
This avoids building stable/11/
from a head/ context.

More direct jail use may be similar.
(I've only used jails via poudriere.)

Unlike for, say, stable/11/ vs.
stable/10/ there could be temporary
periods for head/ for which some
COMPAT_FREEBSD*'s might not work,
even if such is normally avoided.
This is a risk vs., say, stable/11/
running a jail that has a
stable/10/ world.
