How should follks migrate from linux_base-c6 to linux_base-c7?

[David Wolfskill]

As noted in
<http://docs.FreeBSD.org/cgi/mid.cgi?201912302038.xBUKcol9050658>,
the -c6 ports "expire tomorrow."

I don't see a documented process for migrating from linux_base-c6 to
linux_base-c7; perhaps I'm being thicker than usual.

For example, from prior migrations (e.g., the 20141209 entry in
ports/UPDATING), there's a mention of:

|  2. Persistently update the Linux kernel version in /etc/sysctl.conf:
|
|     compat.linux.osrelease=2.6.18

and since there has (as far as I know) been no indication that that
should be changed, I still have it (in stable/11, stable/12, and
head).  But
<https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/linuxemu-lbc-install.html>
does not mention a compat.linux.osrelease sysctl value at all.

I had asked about the migration process Fri Sep 30 20:30:24 UTC 2016;
at the time, the response was:

| We are still working on the other c7 ports:
| https://reviews.freebsd.org/D7886

but I have seen nothing further about the migration process itself.
ports/UPDATING entry 20190710 does discuss the "c6" Linux emulation (but
not "c7").

So: how should a system that has been configured to support
linux_base-c6 be migrated to support linux_base-c7?

Thanks.

Peace,
david

At least Trump can count on McConnell and Putin to "have his back."
And the rest of us can consider what that means about each of them.
