Bug#579522: tasksel - Removes packages without consent

[Serafeim Zanikolas <sez@debian.org>]

Hi,

I see two approaches here. Run aptitude in simulation mode, parse the output,
and ask for user confirmation if any removals are required.

Alternatively, tweak aptitude to not install any packages that require
removals. I don't know or use aptitude but from the little I've looked into
the manual, it looks that the default setting for
Aptitude::ProblemResolver::{Safe-Level,Resolver::Remove-Level} is already set
to the safest value (10000). Perhaps I've missed a way to just say "don't
install packages that require removals" (but wouldn't that defeat the whole
point of tasksel?)

Cheers from the mini-conf at paris,
Serafeim
