I am suggesting to have a global flag called iSCSI while installing(like
other flags "askmethod", "updates"), so when installing the user should
tell the Anaconda explicitly to get the values from iBFT.
Would it be easier if there was a /sysfs entry that told anaconda
about the presence of iBFT? And if there was any pertinent information then
anaconda would extract the information from /sysfs instead of searching in
/dev/mem?
There's already something sortof like this. The current ACPI spec
reserves the table name "IBFT", and Intel has a patch (I _think_ they've
posted it already, but I'm not sure) that gives you access to all the
ACPI tables that exist on the system as binary blobs in
/sys/firmware/acpi/table/ . So if the system firmware is implemented
correctly, then you shouldn't need to ever touch /dev/mem (which as
we've mentioned is dangerous and unacceptable.)
What Prasanna is telling us, though, is that the system firmware (on
some system he's concerned with; I'm not sure which that is) doesn't
actually implement this.
This could also have the extra benefit of initrd shell script being
able to parse the /sysfs and constructing the pertient iSCSI target
information dynamically (and running iscsiadm with those gathered
date) instead of having the values hard-coded as they are now.
That's the high-level plan, yes.
