The idea was to "make buildkernel" once and "make buildworld" once and install to two different DESTDIRs.

I assume your "merpemaster" is a typo for "mergemaster"?

I would have done each step for main installation and then for USB stick (DESTDIR=/mnt) before going to the next step, or maybe that doesn't really matter?

I think the second "mergemaster" was supposed to be done before "make delete-old", or maybe that doesn't really matter either?

I think I must have all GPT modules there; I have no trouble accessing hard-disk partitions, and USB stick when partitioned GPT.

I might want to prevent building ulpt module because of hplip and HP 1212nf MFP printer idiosyncrasies, though that may or may not make any difference.

I could also prevent building other modules that would not be used.
