Hi Natanael

I have followed your posts in gentoo-embedded mailing list. I have only
examined alpine-linux a little, but I'm not quite sure why you use the
tmpfs rather than say keeping with the initramfs and perhaps using aufs
to overwrite with additional packages, and perhaps even adding a
writeable /etc directory? (Actually on the wrt linksys distros they
often add a writable partition with symlinks into /etc, or vice-versa)

Having only an initramfs seems like a very sensible solution for
Michael? He could use a second partition for writable stuff and mount
it rw - then simply symlink in anything required from the static
partition to give a kind of updatable /etc/ (or whatever)

I'm researching something similar myself, but in my case I want quite a
lot of stuff in the base distro (30-60MB perhaps) and so your tmpfs
approach seems like quite a waste when I only have 128 or 256MB or ram
on the devices I want to use...?

Anyone else got any other thoughts on this?
