[xen-tools-dev] [PATCH] Use dom0 resolv.conf when chrooting

[Stéphane Jourdois]

Hi,

Thanks for merging my first patches and adding me to AUTHORS :)

I updated my merge-request after a rebase on your tree.

Another commit is on my tree (not in the merge-request for the moment)
to provide the roles/resolv script as mentionned before.

When those will be reviewed (and merged/rejected), I'm going to
implement further patches to permit configuration of multiple vifs.
I'm still asking myself how to do it so that :
 - config file remains simple to edit ;
 - old config files continue to work as before ;

I see two solutions :
 - add ip2,netmask2,...,ip3,netmask3,etc :
   this is _not_ beautiful code, but works, and xen doesn't support
more than 3 vifs anyway.
 - add a new config option "vif = {ip, netmask, broadcast, gateway}"
where gateway can be empty
   _deprecate_ options "ip", "netmask", "gateway", "broadcast", but
use them if they are present.
   this is my preferred solution.

Feel free to comment as usually !

Stéphane (kwisatz) Jourdois.
