Now for the more controversial stuff. Here's what I would like to see
happen in this area for F10. All these things are open for discussion,
so jump right in.
As a user, I'd like to see automatic installations easier. Here are some
ideas I have.
1. Look at local media (floppy, usb, ??) for a ks file. If one is found,
use it. By way of reference to another authority, this is what Windows does.
2. Request, and use if supplied, information from DHCP. Vendor Options
are specified - http://www.iana.org/assignments/bootp-dhcp-parameters
see tag 43 - as available for vendors (Red Hat, Fedora, Debian) to
request and obtain information from a DHCP server. Anaconda already sets
the option vendor-class-identifier and I use that to provide a special
range of IP addresses for installation:
class "anaconda"
{
match if substring (option vendor-class-identifier, 0,
8) = "anaconda";
option vendor-class-identifier "anaconda";
}
and
pool {
allow members of "anaconda";
deny members of "pxeclients";
default-lease-time 900;
filename "http://Fedora.demo.lan/5/i386/os/Fedora/";;
max-lease-time 1800;
range 192.168.9.170 192.168.9.179;
option log-servers 192.168.9.4;
}
This illustrates how ISC DHCP 3 may be configured to provide information
to Anaconda.
A sane value for filename might be the install URL, or the ks file. Use
of other information such as log-servers, time-offset and ntp-servers
would be beneficial (the filesystem would have correct timestamps that
really reflect the time of the install).
Implementation of one or both of these would mean that users could do
automatic installs with standard media, without having to key
potentially long and fairly meaningless strings of data such as the URL
to an install server.
Problem: If the user booted off a CD and we don't have any method
configuration screen, the implied updates.img and product.img checks
will never work.
In the case of a ks install, this info could be in the ks file. If DHCP
were used, the DHCP server could be configured to provide the information.
