Under section 2(c) of the GPL it isn't really an option:
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
And of course RedBoot does print that sort of announcement (copyrights) and
has done from the outset. It's been strictly incorrect for RedBoot not to
comply with 2(c) for as long as it has (since the RHEPL->GPL+exception
switch). It does seem an appropriate thing for RedBoot to say too.
If anyone has any suggested improvements to make the wording more concise
while still meeting 2(c) and being clear, I'd welcome it - I only made it
up based on a mixture of what other GPL'd apps say, the 2(c) requirements,
and the fact the eCos licence is not in fact pure GPL. Despite the example
at the end of the GPL, I was not keen to include the full licence text via
a special command, and I don't think that's a hard obligation.
Of course due to the exception at the end, I would not expect an eCos
user's own interactive application (not related to RedBoot) to do the same
