This changes the network config to run dhclient from within udev, and
allows multiple dhclients to run at once. It also sets the hostname and
adds a kernel command line option 'netdebug' to help debug network issues.
All modules now live in a subdirectory /modules.d. Each module is
self-contained -- it should contain everything that it will install
on the initrd. All modules must include a script named install, which
will be sourced by dracut. This script should do the actual file installation
using inst methods. The moddir variable will point to the full path to the
module dracut is currently working on.
As usual, this patch series applies on top of my previous patch series,
and is available as normalize-modules from http://git.fnordovax.org/dracut.
Static interfaces are still configured on the fly as we add them, but
discussions on the mailing list have suggested that we need to have finer
control over bringing up dhcp interfaces.
The default hook just runs all the requested dhclients in parallel and waits
for them to all return. If you need something more complicated than this, or
need to have more control over bringing interfaces up, you will probably need
to override some stuff in the 40network hook.
Provided that you are configuring them via DHCP. RARP, BOOTP, and static
configuration are not written yet.
Also, adding nic drivers really bloats the initrd.
I am looking for feedback on these patches from people who actually implement
booting over the network. This patch series does not include support for that
yet -- you will not find nfsroot= handling, or booting to a fs supplied by
dhcp yet. I do want to make it as easy as possible to add support for booting
over the network, as well as making it easy for people to customize things to
meet their site requirements.
This patch series is also available as the network-configurability branch at
http://git.fnordovax.org/dracut. It may be rebased without warning to keep
it in sync with the rest of dracut.
