I agree. Especially with the last part.
Thus, we need to:
1) fix and stabilize packages necessary to create an initramfs,
2) prepare really good instructions for creating one,
3) prepare a news item for users.
For the case of really simple initramfs mounting / and /usr only, I can
even create a small tool on klibc if anyone's interested.
