Hi

you also need the "-u" option to specify MKUPDATE=yes

As from about 2013-09 I've been using sysutils/sysbuild
which uses still broken script sysbuild4cron to schedule 
automatic builds. I tried configuring to build all of 
nbsd-6/i386, nbsd-6/amd64, nbsd-cur/i386 and 
nbsd-cur/amd64 but that ground to a halt due to memory
and swap exhaustion so I split to have four separate 
build directories, 20G each (much duplicated wasted disk
space), and that works very well. I've added a script to 
put kernels and sets into a "latest" directory which is
then used by a system update script.
