I've used that approach sometimes and regularly recommend it.

That said, my main intention is to *debug* the problem, i.e. to
provoke an error message in some log file or whatever, to learn which
process is (undesirably?) mutating some file. Most of the time this
leads to learning some config option to not do that mutation in the
first place (or to some understanding on why that mutation is a Good
Thing after all and to a better way of solving my real, underlying
problem).

Only in exceptional cases I had to "leave in" the immutable attribute
as a permanent "solution".

(as to the rest, yeah, resolvconf seems a worthy candidate).

Cheers
