Default find has a builtin delete action. Use it instead of exec'ing rm.

How portable are you looking for?

Portability is not an issue. The beauty about this is that we can simply
assume we have GNU tools and we do use Linux ... because that is what
Arch is based on.

I have no problem having GNU-specific features in there, as we can rely
on GNU find (or GNU whatever) being present. The only exception is
initramfs - however, no shell script is used in both the system and
initramfs.

Well, it's basically what I did in mkinitcpio 0.6. I dumped klibc and
all the packages that used it in favor of pure glibc binaries.

However, I still use busybox instead of util-linux-ng and coreutils: It
is much more convenient to just run "busybox --install -s" and have a
fully functional environment than having to collect all the basic tools
and make sure they are installed. The maintenance effort for busybox is
almost nonexistent, and it offers many tools that you wouldn't install
into initramfs otherwise. I am convinced that this is the best of both
worlds, I get a feature-rich and very very small initramfs environment
this way.

Anyway, this is OT in this thread and we probably shouldn't pollute it
with this discussion.
