Not quite. They mainly have to edit and update their environment.
If Linux user space references any partitions, that would have to
be edited as well.

So this would be the type of change that causes all sorts of upset.

Sure, but if you create weeks of extra work to save a couple of
hours, that's not good either.

Well, just don't actively break anything. It's easy to fix things
that might slip through. It's hard to fix things if the breakage
has become a design goal.

I'm looking forward to the day when the devirginator has to support
a dozen different product lines ;-))

The enhanced envedit.pl is in SVN revision 3729. I've also added
macro expansion, just in case.
