   Here is an updated patch which is fully functionnal: the RAMdisk name is
   retreived from DHCP, we grab it through TFTP and we use it. 
   http://ftp.espci.fr/shadow/manu/tftproot2.diff
   
   There is work remaining to be done (Remove the nfs_boot code from NFS so
   that TFTPROOT has no dependency on NFS, load gzip'ed RAMdisk, TFTP with 
   larger block size), but I beleive the code is actually usable and useful.
   
   Any objection against the above patch beeing committed?


it seems to me that this is duplicating a lot of what is in libsa.
infact, the patch has at least comment to that effect.  i wonder if
there is a better way to share this..


it seems that you call realloc() for ever incoming packet?  that
seems suboptimal.


i believe nfs_boot.c will fail to compile (unused "out:" label)
when TFTPROOT is not defined.
