it looks better now, but bash as initramfs /init program does not seem
to work. is anything special required to get an interactive shell?
as with cramfs I have an /dev/console device, and that was enough,
but with initramfs the console stays silent.

also is there any alternative to klibc?
I currently have a big fat ramdisk of about 4 MB with
glibc, bash, ssh, openssl, dm-crypt, opensc and openct
(smart card tools), and because of that long list of
applications, I have no use for a small c library.

is initramfs limited in any way? or will increasing
CONFIG_BLK_DEV_RAM_SIZE allow me ram disks of any
size? about 20 MB can hold a very, very luxurious
environment ... :-)
