Re: RFH: dropbear initramfs support

+1, thanks for maintaining the package!

Also I have a small note that may be useful for someone (?):

I recently experimented with dropbear in initramfs for another task - I  
wanted to have a "rescue" ssh on a non-standard port available all the  
time, even if initramfs can't mount the root filesystem. I was very happy  
to discover initramfs support in your dropbear package :-) the idea itself  
was rather simple, I've just removed the dropbear stopping code from  
initscripts, changed 'run-init' to mount --move + chroot / in 'init'  
itself, and mount --move /dev and /dev/pts to mount --bind. The result is  
interesting - when you login to dropbear, you appear inside the old root  
(rootfs). At the same time:
* cd / --> you stay in the old root (rootfs)
* ls /.. --> the new root is listed
* ls /<any_dir>/.. --> the new root is listed
* cd /.. --> you stay in the old root
* mount --move /.. /root --> most interesting: the new root gets moved  
into /root on rootfs, and the rest of the system runs like in a chroot -  
not because you ran chroot from there, but because the root has moved  
itself :)
