Good point. The advantage of depcleaning a particular package is that if something does depend on it, emerge will tell you what, and you may decide to remove or change flags on the dependant package. With deselect, if the initial package is still wanted, the subsequent depclean will do nothing silently.

Both methods require two commands, so mostly there's no real difference; and in this case depcleaning python:$SLOT is probably better as it's essentially saying you want to explicitly remove it if it's not required; but for normal packages (or multiple packages - it's quicker) I personally prefer deselecting then depcleaning.

It builds them automatically for you as you emerge things. I've had a close call or two so I have had that set for many years now. If you do set that, remember to use eclean-pkg on occasion if you start using a lot of hard drive space. You also may want to look into eclean-dist too. ;-) Dale :-) :-)

Yeah right.. this is not going to change any faster than people are going to abandon dual homing ipv4 and ipv6 let alone ipv4 all together. Absolutely hopeless, some people just cannot be convinced (shouldn't be allowed to use a computer) a lot of people simply don't have the time. I foresee python being dual stack indefinitely without cross compatibility. When the day comes and you prove me wrong, I owe you $20. But... the need for python 2.7 has to be COMPLETELY eliminated and just saying RIP Python2.7 or gtfo doesn't count coming from any source. -Paige
