I'd agree that this is the preferable solution.
While we *could* modify fmtutil, along the lines of the patch I
showed, I absolutely agree that the cost and risk of doing this so
close to TL2006 release is a major concern. And it's difficult to
predict how many complications and support issues may arise "in the
(a) ConTeXt is the only package where this is an issue
(b) it runs tex engines via scripts that have the opportunity to
configure the setup appropriately
(c) users are therefore not directly exposed to the exact name of
the .fmt (or engine) used
I think it would be best for this to be solved by ConTeXt using
engine-specific .fmt names.
PS: About to send, but just seen Taco's message "Don't go blaming
context...". True. It's not a question of figuring out who to blame,
but of looking at the big picture and finding the best way forward
from where we are. I think, on balance, that a change within ConTeXt
would provide the best solution at the least overall cost. Then
fmtutil can maintain the ConTeXt formats alongside others without
other infrastructure changes.
Another option is to do nothing, and let ConTeXt formats be managed
entirely separately from the others. However, I think this will tend
to leave ConTeXt somewhat marginalized in the TeX Live world, which
would be regrettable. I'd like TeX Live to be much more than just
LaTeX Live. :)
