I am compiling an initramfs from minimalfs and it fails to detect init during boot.
I have 2 simlinks one at /init and another at sbin/init both pointing to /sbin/init.sysvinit
I just have tried passing the filesystem directory as well as the cpio in the kernel config. The following is the tail of bootlog:

The init was an elf binary with dynamic libraries linked to it. I found it by using readelf -d on the init file. So I needed to add the libc library that I thought would be linked statically in init. Big thanks to "that toher guy".
