[syslinux] PXE and initramfs

[vovan at planet.nl]

Hello,

I'm trying to switch from initrd to initramfs for diskless  
workstations, but I have some problems. I just made a symlink /init ->  
/sbin/init and gzipped cpio file, then tried to compile image in the  
kernel or use image with initrd option. In the first case I'm getting  
"corrupted or invalid kernel" immediately. In the second kernel and  
initrd can be downloaded but at the certain stage I can see only  
repeated message "udevsend: error ...".
Which additional steps I should take?

Regards,
Vlad.
