netbsd sources but i could be wrong on that point.
You are correct. FreeBSD has it's version of the same shell in /bin/sh.
The Debian ash package is based on an old version of NetBSD's sh.
Unfortunately, Debian installs /bin/sh as a symlink to /bin/bash.
Supposedly, /bin/sh is supposed to be "a Posix-compatible shell," but in
practice Debian sources and scripts may fail when /bin/sh is changed.
FreeBSD sources fail to build with /bin/sh set to /bin/bash. I basically
do s#/bin/sh#/usr/bsd/bin/sh#g right now. Later I may try using the ash
package. I'd still have to change the sources.

sh is one of the tools it needs to build the source. There are several
skaro:/# ls /usr/bsd/bin
byacc gcov kas kgdb kranlib make patch yacc
colldef gensetdefs kc++filt kld kreadelf mkdep sh
compile_et install kcc knm ksize mknod tcsh
csh kaddr2line kcpp kobjcopy kstrings mktemp tsort
find kar kgasp kobjdump kstrip objformat xargs
And yes, all of these are things for which I can't presently substitute
the regular versions of these from Debian packages. :(
Several of the tools are there because they have incompatible options to
GNU versions. find and install for example. Others are apparently
BSD-specific, like gensetdefs or compile_et.
(dunno about gensetdefs, but compile_et is part of kerberos.)
There are several tools that I'm not precisely sure what they're for,
but found that building FreeBSD sources without them fails. Basically I
kept trying until I found all the tools wanted, and the build worked.
FWIW, in netbsd-current, basically everything is cross buildable from
several platforms (netbsd-current, netbsd 1.5, freebsd, linux,
solaris, maybe more...) this is possible because we now build "native"
versions of all these tools before building the world. i heard a
whisper that freebsd is starting to be interested in cross compiling
(it was a reason to ditch perl as part of the base) so maybe they'll
get to that point eventually. in the netbsd source tree, see both
src/build.sh and src/tools... the former is a frontend script to building
stuff without having to know all the magic variables to set, etc., the
latter consists mainly of Makefile's to build native versions of tools,
eg, for lex we have:
They have a lot more to do. :(

(those ktools things scare me... i wonder why they need special
kernel wrappers/programs for all the toolchain bits...but i think i'd
be scared by the answer :-)
FreeBSD patched binutils and gcc and didn't merge upstream. Some of the
patches are downright stupid, IMHO, like the one to binutils to set
The kcc, kas, ksize, etc. aren't wrappers, they're actually gcc, as, and
size from the FreeBSD source tree. I renamed them and stuck them in a
different directory to try to make sure that they don't get used by
mistake instead of the system ones. Unfortunately, I haven't tracked
down all the things that have been done to them yet, so I have to use
the FreeBSD versions to make sure my kernels work...
