2004-02-19 Brett Johnson <brett@hp.com>
* Fixed bug where default image initrd would carry over to another
image that was selected interactively (iff the newly selected image
did not have an initrd).
* Added support for subnet-specific config files in netfs.
2004-02-17 Brett Johnson <brett@hp.com>
* integrated ia32 compressed kernel support from Matt Tolentino
<matthew.e.tolentino@intel.com>
2003-08-20 Stephane Eranian <eranian@hpl.hp.com>

- Convert all filesystems (ext2fs, netfs) to use the FilesystemProtocol interface instead
- cleanup x86 loader: use the same structure as IA-64

This filename is an opportunity to specify a machine specific configuration file.
2) elilo-ia32.config or elilo-ia64.conf
2) AA[BB[CC]][-ia32|ia64].conf
As of version 3.5, elilo will also look for IPv4 class A,B,C
subnet-specific versions of the config file. This is useful when you
want to have a common config file for all machines connected to a
particular subnet.
For example, if your IP address is 10.0.0.1 (0A000001 in hex), elilo
will look first for 0A000001.conf, then 0A0000.conf, then 0A00.conf,
and finally 0A.conf.
Elilo will also try architecture-specific versions of subnet-specific
config files first (So for example, on an Itanium system,
"0A0000-ia64.conf" will be tried before "0A0000.conf")
3) elilo-ia32.config or elilo-ia64.conf
Depending on the machine (client side) architecture elilo will try the IA-32 or
IA-64 file.
