Of course, because release(7) runs built userland; in your case it runs userland with FreeBSD 13 ABI on FreeBSD 12.x host. > I need to see how it works with `make release` :-) This is what I meant when saying "you can build the source tree for 13.0-CURRENT on 12.1-RELEASE"; sorry if I've confused you. Check ``Building with release.sh on -STABLE'' thread[1] on the forum.

"2h looks really cool" because release(7) may build chrooted build environment, where it then may build port(s) and builds the target. My Xeons usually spends 1.5 hours on clean release(7) (with 16 make(1) jobs). > 94556.462u 5583.273s 1:43:14.24 1616.6% 50234+3336k > 1457023+16921354io 615421pf+0w > -j12 94477.001u 5577.692s 1:42:59.60 1619.1% 50251+3337k > 1463964+16932952io 617689pf+0w > -j24 94480.274u 5574.117s 1:43:38.89 1608.8% 50213+3336k > 1468685+16931170io 617425pf+0w > -j48 94588.653u 5569.909s 1:43:10.62 1617.9% 50211+3336k > 1460546+16925145io 611229pf+0w > > These times may be even smaller when SSD is used instead of HDD.

By installing additional CPU(s) which will allow you to run more make(1) jobs in parallel. My -j16 builds consume about 16-18 GB (at peaks). > I > saw some ramdisk tricks I need to try that as well :-) > > Best regards :-) > Tomek > [1] https://forums.freebsd.org/threads/building-with-release-sh-on-stable.70889/
