I'm trying to upgrade FreeBSD from 11.1-STABLE to 12.0-CURRENT by building from source. In the middle of build process just before switching to chroot I get following error:
"UNAME_r and OSVERSION don't agree on major version number"
Same error I got when tried to upgrade from 11.3-CURRENT to 12.0-RELEASE on my T430 laptop. Then I had to reinstall OS from scratch.
Is it possible to solve the issue without OS reinstallation?
