I fully agree.
I have even tested this some time ago, but I have not submitted a
pull request because I was not sure how to check whether dolfin is
compiled with petsc-dev in python (for conditional running of
examples and tests).
And also I was thinking you prefer to wait for next petsc release
(there were some minor adjustments in progress in the TAO interface
inside petsc).
Garth may you do this or you want me to do it? Eventually I may try
to find some time next week, but not sure.
That would be great. No urgency.
About TAO, I think it could be also useful to add the full nonlinear
TAO solver, like for SNES.
Differently from SNES, TAO requires also the definition of the
functional to be minimized in NonlinearProblem (not only gradient and
hessian). Otherwise the interface is very similar to SNES. The reason
for which the current interface is only for quadratic functional is
mainly due to the fact then when I added it SNES solver interface was
not existing (and also that I was mainly interested in the quadratic
problem ...).
What is your opinion about that?
Sounds good.

TAO has recently been merged into PETSc-dev, so to keep things
simple I propose that we drop support for TAO as an optional
dependency package and just configure it via PETSc. This means for
now that users of DOLFIN-dev will need to use PETSc-dev to access
TAO, and from the next PETSc release TAO will be available to all
users who configure DOLFIN with PETSc.
Let me know if you object to the proposed change.
Sounds very reasonable.
