Personally, I use native "make buildworld buildkernel" and
let it run over the weekend. ;-)
I know a lot of people are happy with NFS mounts, but
here are two other options that may prove attractive
to some people:
* For systems that boot from SD card:
Cross-build a new system, mount the SD card onto the
build host, and then update the SD card image with
make ARCH=armv6 DESTDIR=/mnt/ installworld
* For BBB that's booting from eMMC: I've considered
adding an option to Crochet's BBB images so you can build
a new SD image, boot from that, then update the installed
system on eMMC with bits from the SD card. Such a
script would complement the existing "copy-to-emmc.sh"
script which erases the eMMC and copies over the
SD image.
Re: several complaints about SD cards and speed.
A good USB reader/writer can bulk write to an SD card
at better than 10MB/s. (That's a full 1GB image in
about 2 minutes.) I've used the built-in SD adapters
in various laptops, but those always seem to be really
slow. It makes a big difference.
