I didn't know you were interested in my arguments... they can be read
here:

I read the thread it was mentioned when I first asked for feedback, which
was this:
http://lists.debian.org/debian-devel/2011/11/threads.html#00281
But to be sincere, I don't remember "all" of the contents of the posts
nor "who" posted there "what"... and now you tell, I can't see any post
belonging to you in that thread. Maybe you made your comments afterwards?

Thanks, firt time I see. I didn't know about it...

"Unspecified size"?
It was just the kernel source (75 MiB). Wow. How. Big. >:-)

I doubt it becasue I tend to put special care for that can't happen (my netbook
has a 250 GiB. hard disk with only 2 partitions: /swap (2 GiB) and "/" (the
remaining space). Since I returned "/tmp" to the root filesystem I've had no
more "hiccups".

Yup and I fully agree with you in this. That's why in my first post
("[Feedback needed] Setting the right size for /tmp") I asked for
"feedback" and I wasn't complaining at all for this setting.

Yes! And I already wrote some things that we should care about for this
is introduced in Wheezy "smoothly".

Glad you ask. I already mentioned some points here:
http://lists.debian.org/debian-user/2012/03/msg01857.html
***
- The installer (at least in the "expert" flavour) allows the user to
enable/disable this and/or set a default sane value for the "tmpfs" size,
being automatically or manually set.
- The upgrade routine asks the user for this change so this is not being
applied silently but consciously.
- This new setting is documented in the Installation Guide so people can
be at least aware of this option, how can be configured, how can be
turned off, and some user-case examples so they can make their own
estimatations based on their system configuration and needs.
- A simple tweak for modifying this option once the system has been
installed (this is already done) and how it could be applied on the fly
without rebooting a running system.
