Long story short I need 13-CURRENT to create a 13-CURRENT release with
release(7) because on 12-STABLE/RELEASE chroot with 13-CURRENT does
not work. I need to see how it works with `make release` :-)

Will try that `make release` as well, also for 13-CURRENT on
12-STABLE, thank you! Also will compare the time cost with the one
presented below :-)
Creating a "release" also has this advantage that I have memstick
images that I can boot from directly, test what I need, even no need
to install :-)
Here are my build times, for a release for AMD64/12-STABLE, I did not
select DOC nor PORTS to build, only Kernel and Base :-)

These times may be even smaller when SSD is used instead of HDD. Also
I wonder how to utilize all RAM to speed up the compilation because I
can see 8..34GB utilization while the rest of 128GB remains unused. I
saw some ramdisk tricks I need to try that as well :-)
Best regards :-)
