[9fans] plan9.ini: ipconfig and bootargs

[tlaronde@polynum.com]

Hello,

When trying to re-install a Plan9 on a new node, being unable, with the
kernel compiled present on the CDROM image, to access a FAT or an iso
image of a root file system, I went to a combination of a minimal sketch
of a plan9 slice, with a 9fat made "by hand" (from an already installed
other OS---here NetBSD) and access at boot time a remote root
filesystem, for the installation, serves by another Unix node serving
9P2000.

The surprise is with the bootargs, in plan9.ini, supposed to configure
the network for the node, in order to access a remote root filesystem,
as in:

fs=192.168.1.3
# auth not used
auth=192.168.1.3
bootargs=tcp!-g 192.168.1.1 gbe 192.168.1.2 255.255.255.0

what is after the '!' being supposed to be args to ip/ipconfig.

The problem is that the gateway is taken as _another_ ip address for the
interface! and that the mask is taken as the "node" serving the root
filesystem! "fs" not being taken into account.

Only:

bootargs=tcp!gbe 192.168.1.2

works...

Is the ip/ipconfig embedded in boot reduced as to not take all the
options? (I don't need them; but the wiki page is the wrong; and
I wonder if I'm doing something wrong or if there is indeed something
changed since the page was written...)
