Hi,

The thing is, it only have a 128M flash disk (seen as /dev/da0)
GENERIC needs almost 250M.
I have run into something similar, while building a ZFS install to run
on an Intel SS4200EHW NAS device. Utilizing a series of scripts I have
developed[1], I was able to compact an entire functional FreeBSD system
into 4.6MB /boot and 84MB root with mkisofs and mkuzip, without
permanently tying up a bunch of the machine's limited RAM with an MFS,
and with acceptable performance despite the IDE channel's speed limit of
1.6MB/sec. Plus, boot and root are read-only, so the CompactFlash card
won't wear out prematurely.
You can make use of src.conf(5) while building world and kernel to
eliminate a lot of unnecessary userland components, and MODULES_OVERRIDE
and WITHOUT_MODULES to control what modules get built, as the kernel
build process will build all modules regardless of what might be in your
kernel config. Be prepared to perform lots of testing, though, as a
missed critical dependency can appear to succeed, but leave something
else broken.
I do believe you can omit the *.symbols files. I plan to try it
myself. Would someone please confirm this?
And you might look at resurrecting the picobsd method of crunching
binaries into one single statically linked binary with hard links of
differing file names if you want to get really small. I used to do this
when compactflash was only 128MiB.
Thanks,
