DOC2k booting speed ...

Hi,

Thank you for your quick answer

As I cannot use JFFS2 with the DOC, I use an initrd to put the whole system
in ramdrive without having the doc mounted. 
I did it to avoid filesystem failures. 

Is there another way to 
 1) boot from the DOC, 
 2) build up the OS filesystem 
 3) umount the DOC ? -> protect filesystem in case of unexpected powerdown

I saw many things about pivot_root but didn't found any simple example to
get started.

Thank you.
