Yes, please consider doing that, it sounds pretty effective.

I think it would be nice to avoid even that, it takes up lots of disk
space, see [1] which makes Fedora somewhat less appealing for embedded
use - such as OLPC where there probably is still a few statically linked
binaries that are completely useless on such a system.

Note that SUSE just includes the glibc and other required DSO's in the
initramfs; I did the same for my livecd stuff (that has a rather
complicated initramfs to setup dm-snapshot for rw rootfs) and it works
very nicely.

So it's definitely possibly but I'd expect some resistance from certain
package maintainers :-)
