This reduces the ramdisk installer size with a few megabytes when gzipped,
but with about 40 MB when unpacked in memory.
There are a few improvements possible:
- strip the binaries. This saves another few MBs.
- only copy the binaries we really need to /bin or /sbin. This could reduce
the size of the installer a lot, especially with util-linux, of which we
don't use that many tools at all.
- try to move some packages we link with glibc right now (like util-linux) to
dietlibc. This will not work for bash, already tried that.
- try to use busybox as a replacement for everything.
