For those of us from FreeBSDland, the kernel upgrade process is (well, recently) solidified to a number of steps including
mergemaster. Matt Dillon noted that the DragonFly upgrading process is thus:
(update via cvsup)
make buildkernel KERNCONF=<kernel config file>
make installkernel KERNCONF=<kernel config file>
The “make upgrade” step replaces
mergemaster, and should be relatively faster. Credit for this goes to Sascha Wildner for asking for clarification on the dragonfly.bugs mailing list.
