My plan is to continue with 4-STABLE for a while, and try building CVS
snapshots of 5 every so often. Once I get one that builds ok, I'll have to
recompile with the new libc. I made a DBS-like package, so it's not too
hard to change over to -CURRENT.

I'm not in a real rush with it now, because -CURRENT is getting changed
rapidly, and I'm trying to concentrate on making a working Debian system.
What I'd like to do is get my system working well with -STABLE, and get
the base changes merged into Debian. Then playing around with -CURRENT
would make more sense to me.

Otherwise, I'm combining an unstable userland with an unstable libc and
kernel. That's just a bit too hard to debug.

I've had a few headaches. Here are the major compatibility issues I've
found:

	1. getopt_long not in libc. Sometimes alloca, too. Some
		Linux/Debian specific programs are not checking for
		libiberty functions in configure.
	2. unicode/iconv support not in libc. It seems to be missing
		multibyte character support.
	3. utmp is missing a lot of fields. I solved this by writing
		a utmpx implementation.
	4. shadow passwords. I'm writing a library that will hopefully
		solve this.

makedev is apparently incompatible with bash. ash works, and so does /bin/sh
from FreeBSD. I just used ash. In 5.0 that goes away, because of devfs,
so I'm not too worried about it.

My solution was to make a directory /usr/bsd, and I put programs into
/usr/bsd/bin. It looks like this:

skaro:/# ls /usr/bsd/bin
byacc       gcov        kas       kgdb      kranlib   make     objformat  xargs
colldef     gensetdefs  kc++filt  kld       kreadelf  mk_cmds  patch	  yacc
compile_et  install     kcc       knm       ksize     mkdep    sh	  yyfix
csh         kaddr2line  kcpp      kobjcopy  kstrings  mknod    tcsh
find        kar         kgasp     kobjdump  kstrip    mktemp   tsort

Everything in there was basically required by the FreeBSD Makefiles. When I
build FreeBSD, I put /usr/bsd/bin in the front of PATH, and it works
fine. (I also set CC=kcc, when building the kernel, because I haven't
been able to get it working with the Debian gcc and binutils yet. If
that gets fixed, a lot of that stuff can go away.)

Everything under that directory tree lives in a binary package, called
freebsd-buildutils. That package is built from the FreeBSD sources, and
is a build dependacy for those sources. That's not pleasant, but it
works well. If you want to rebuild the FreeBSD parts of the system, you
install that package.
