I have two objections to this argument:
(1) If tlpmgui's automatic guessing the correct mode (installation vs
maintenance) is intended to help avoiding with old / incomplete TeX
installations I find the current behavior not ver y helpful: Since
tlpmgui does not provide any hint what has it caused to start
maintenance instead of installation mode I thus only know that
"something went worng" and nothing more. A more verbose message with
more details (something like "ther is alread a TEX in Path ..." or so)
would be in my opinion much more helpful.
(2) Beside point (1): In my opinion every powerful tool should be an
expert mode where the user has all available options under his
control. Of course for such a power a price has to be paid: You are in
the risk to damage soething or even everything It's just the mode "I
know what I am doing". This is one important reason why I prefer under
UNIX the archaic "install-tl.sh" for TeXLive setup. (And, by the way,
for the very same reason I would never use GNOME although I always
recommend it to UNIX / Linux newbies.)
