Depending on the desired semantic this could be more or less trivial.
If we want /etc/flash-kernel/local.db (say) to require stanzas indexed
by machine just like all.db then it seems like it should be sufficient
to make MACHINE_DB into a function:
if [ -f /etc/flash-kernel/local.db ] ; then
echo # ensure a blank line between local.db and all.db
This might seem a bit odd since you would require the Machine: line even
though it ought to be obvious it applies to this machine, e.g. you'd
Machine: Globalscale Technologies Dreamplug
to override DTB-Append. The flip side is you could override different
settings for different machines (which seems fairly useless to me.
It'd be a bit more code, but still pretty trivial to
parse /e/f-k/local.db in all of the places which currently just parse
$MACHINE_DB it, so you could just provide "DTB-Append: no" in the config
If you let me know your preference I'll hack something together.
