I am thinking of implementing something like this in
kernel-package. Ideally, I would like to support things like:
a) Specify a range or a single kernel version that the patch applies to
b) Specify a patch version
c) specify patches (with versions) that one depends on, these
patches need be present, and shall be applied before the current
patch
User should be able to specify a list of patches that they
want to apply; and have all the dependent patches pulled in, or warn
that patches could not be applied (not-present; failed-depends); etc.
The patches applied would be unapplied in reverse order on
clean up.
I am thinking of a generic run-parts replacement with
versioned depends; so that this work be useful beyond
kernel-package.
