Hi Nick,
sorry for keeping silence. I was going to try your scripts when I have
found another bug...
But I suspect that you have made some modifications to nanobsd.sh as well.
You check if the variable NANO_LABEL has some value after sourcing
/etc/nanobsd.conf,
but FreeBSD-standard nanobsd.sh doesn't write NANO_LABEL in the config file.
Additionally, there is a problem that after dd'ing the image manually
onto the correct partition,
you won't have the required disk label on it. See:
# glabel status -s
ufs/FBSDFLTs3 N/A ada0s3
ufs/FBSDFLTs1a N/A ada0s1a
ufsid/52a44002fa6458ff N/A ada0s2a
The last entry is automatically generated UFSID label, because the
_.disk.image that is generated from NanoBSD
build doesn't have any label on it -- it is also logical, because the
build system doesn't know which partition you
will be upgrading.
