I just joined the list so I'm sorry if this is not the proper way to
propose or ask for a feature to be added to systemd. I spoke in
#systemd on Freenode a few days ago and I was pointed in this
direction for submitting feature requests.
I read this post: http://0pointer.de/blog/projects/stateless.html
It sounds like systemd is working toward a boot situation where /etc
is disregarded in the hopes of using default/safe values (maybe
safeboot?).
Basically I'd like to be able to pass minimal network settings to
networkd from the kernel cmdline on an incidental basis (I don't want
to supersede /etc, I just want to use this for convenience where
possible):
I'd like to have something like this:
sysd.net=eth0:192.168.1.48/24-
.256;eth1:172.16.0.3/16-0.1
I agree, we do want this. If you want to work on it, I suggest first
adding support for reading the kernel's ip= option.
Cheers,
Tom
I've already discussed this idea on IRC with others and it was
negatively received -- everyone who spoke with me resisted the kernel
cmdline becoming the new /etc. I want to reiterate that this is not
what I am after. I want basics passed to networkd, I don't want to
use the kernel cmdline for everything.
Networking is pretty crucial to getting a remote box up and
reachable/ssh'able. Usually I find myself having to vnc in for a
console -- it can be inconvenient to maintain that gateway (imo).
There are distros oriented for being minimally configured and almost
reentrant. I'm thinking of TAILS or TinyCore or the slew of
penetrating testing distros available out there. It would be *VERY*
useful to me to boot an ISO remotely with the networking settings
passed from the kernel cmdline, then ssh in and finish the
configuration.
I'd like to be able to do static IP assignment. I want to have the
ability to use DHCP or enable responding to IPv6 router
advertisements. (It'd also be useful to enable security extensions so
the MAC address isn't leaked in the IPv6 assignment). It may also be
useful to configure wireless interfaces by passing the encryption
method and password -- though having the password visible on the
kernel cmdline would not be idea. -- AGAIN, I am thinking of
incidental/expendable setups -- not long-term management performed
this way.
I hope I've been clear, I've met a lot of resistance with this idea
but I don't think it's terrible. I would simply like more discussion
on its viability.
