How to get & use the iPXE local (current) path ?

[ruymbeke]

Hello
I did read this properly and I really like this relative path feature.
But how can extract this relative path info from a running iPXE session ?
(it must be somewhere in a iPXE variable so we just need to make it available to the user)
As an example to display a menu title with that current path
(which could the result of multiple menu navigation steps)
or have the script to branch based on the current path.
Thank you very much for your support and follow up.
Best Regards,
Gilles

PS: I looked at your complex iPXE menu sample script in here:
https://gist.github.com/robinsmidsrod/2234639 (thank you for sharing it).
You create & update your local variables such as "base-url"
to keep track of the menu changes. But this does not work if the
user do type a new path via the interactive mode (broken history)
and I would much prefer to have a way to really extract the current path.
Is this already possible (if yes how ?) or this feature needs to be added to the code ?
