Ok, here is where I am so far, but my ocaml is VERY weak, so it is slow going, I also added the right stuff to <a href="http://config.ml.in">config.ml.in</a> and Makefile.ml to make it work.<div><br></div><div>it seems to work, but when I run febootstrap --names bash coreutils dcron dhcpcd e2fsprogs file filesystem findutils gawk grep grub gzip initscripts iputils kernel26 less libusb logrotate net-tools pacman sed shadow sysvinit tar tcp_wrappers udev util-linux-ng</div>
<div>it only processes bash.</div><div><br></div><div>I am sure I am missing something obvious, but if you have any suggestions that would be great, learning ocaml is taking some time :)</div><div><br></div><div>-Tom Hatch<br>

So it's almost enough for you to tell me the equivalent of those<br>
commands for pacman, although of course I'd prefer a patch to<br>
febootstrap!<br>

I will grab a git checkout of febootstrap and start looking into prepping a patch, but if this is enough info for you to whip up support then let me know and I will test it and fix any arch specific things.</div>
