I wonder if you could do this: 1. mount a tmpfs somewhere 2. copy in enough libs etc to make #4 work 3. chroot to the new tmpfs 4. set up the bridge and transfer the address across 5. leave the chroot environment You wouldn't want anything much else to be running at this point though so it would have to be done pretty early in the boot process. > I'd prefer to not do it with an initrd, as that's an added step, and extra > complexity. I've set up an initrd that boots dom0 over iSCSI, which suffers from the same problem as nfs only more so as iSCSI is connection based and downing eth0 cuts the connections. My initrd sets up the first bridge (my setup has 3 bridges) from the outset so the network disappearing never becomes an issue. Under iSCSI an initrd is the only option but for nfs it would be nifty to be able to do without. If anyone's interested in the script to create the initrd (debian - not sure how it would translate to another dist) I can post it here, shouldn't be too hard to modify it to boot from nfs... in fact my home pc's boot off nfs using almost the same setup.
