Hi Srinuvasan,
my suggestion would in fact be the same. The layer that brings the wic
plugin should extend the list of variables. I removed them because they
are in fact "bad style". For the upstream plugins i decided to follow
the symlinks to find the actual filenames, something the efibootguard
plugin might also want to consider.
The variables are in fact nasty hacks for the isar testsuite to start
qemu and should have never been used in wic plugins (imho).
So you have the following options:
1. extend wicvars in your layer
2. extend wicvars in the layer with the custom plugin
3. upstream that plugin into isar
Order is ascending in quality/effort/sustainability of such custom
plugins.
