I'll note that my original architecture document[1] contemplated two
kinds of "add-on" profiles:
- ExtensionProfiles could register *new* kinds of steps, as well as
making non-destructive insertions to the configuration created by a
baseline profile.
- DeltaProfiles essentially captured line-level diffs to a "baseline"
profile.
I think there is room for both, where we get away from the need to make
EPs the "current" profile in order to use them. DeltaProfiles could be
"applied" by patching a snapshot, and then installing the snapshot as a
new baseline.
Because not all the files being patched are XML, I don't think we can or
should rely on XSLT: diff might be enough.
Tres.
