By accident?
E.g.. I for one occasionally use to command line to remove whole sets of
packages and these occasionally produce unexpected results or suffer
from typos.
Accident prevention is exactly what these kind of protections are good
for and I see absolutely nothing wrong with that.
What I find disturbing in this (and other similar threads of the past)
is when people are obviously *leaning* on the safety mechanism. The
protection as it exists in Fedora today is not up to that, you can
easily render a system practically unusable in number of ways without
tripping up the yum protections.
Absolutely. Nevertheless, yum's protection is good enough to prevent the
"really stupid" accidents.
It's not that difficult to accidentally type
# yum remove -y python <someplugin>
instead
# yum remove -y python-<someplugin>
For the obligatory car analogy ;) Most people agree that the electronic
stability control (ESC/ESP/DSC/...) in modern cars is extremely useful
and good for catching the occasional minor driver error. It wont save
you from constant reckless driving however.
I prefer the "electric fuse" analogy. No developer with a sane mind
would have the idea to construct a device/tool without fuse and expose
his users to risks of electrocute them.
