We have an extensive build infrastructure around (the original) nanobsd.sh
script here so sharing my .conf file would only be a small part of the
puzzle I'm afraid.
In the .conf file I've set NANO_DATASIZE to the amount of space I want
to use for ZFS, nanobsd.sh will divide the rest (minus NANO_CONFSIZE)
by 2 for the root partitions.
When using a recent nanobsd.sh script, you should redefine the
populate_data_slice function to do nothing in your .conf file,
something like:
populate_data_slice ( ) (
# Don't newfs slice 4!
)
Because I use this on hard drives too, I use a modified
create_i386_diskimage function that only spits out _.disk.image and not
_.disk.full (that would end up to be 500GB for my drives).
If you tell me what flash, ssd or disk drives you are using, perhaps I
can dicrect you a bit further on the easiest way to proceed.
With kind regards,
