My M.O. is: # apt-get update # aptitude full-upgrade # apt-get autoremove Because as far as I can tell, apt-get sometimes fails to actually update things, whereas aptitude can't autoremove. I'm sure there's a better way. This is my major gripe with the dpkg ecosystem. There are (AFAICT) multiple different tools to build dpgks and multiple different tools for updating your system, and none of them are adequately docum…

Others wrote "apt-get dist-upgrade" in sibling comments, which should do the trick. If you want to build packages for multiple managers, fpm is a nice front-end for some of them: https://github.com/jordansissel/fpm

I use FPM all the time, but it is not a 'nice' way to package things, it's an 'easy' way to package things ;)

andrewshadura is right. Here's just one of your items that is bunkum, for an example. > their own custom [...] init system of Upstart when they could have contributed to System upstart was developed several years, just under half a decade, before systemd even existed; it was used by Fedora for three years.

It's true though that Canonical consistently "does their own thing" and then fails to establish it as a standard for whatever reason (technical, political, CLA...). Anyone who adopted the new thing then has to migrate. Eucalyptus vs OpenStack (ever heard of Eucalyptus?) Bazaar vs Git (Git won) LaunchPad vs Github (LaunchPad is alive and well, but Github won the popularity contest) Wayland vs Mir (Wayland won) upstart…

Yeah they invent a new wheel (often poorly) then they fail to test and fix it when it breaks.

Ubuntu actually only keeps the current and the previous kernel as necessary and give the user the option to purge all the old kernels. These old kernels will be marked as autoremovable and by setting a flag in unattended upgrades config you can make it autoremove those. On desktops this happens automatically.

On RHEL, it happens on servers, too - anything is better than your /boot partition filling up on its own!

It shouldn't, the default is to keep 6 recent kernel packages.

It's not just a bunch of people setting cm.swappieness to 0 is it? That behaviour changed and now prevents going into swap /ever/ where it used to mean go into swap as a last resort.

IMHO if you can't not use swap without running out of memory in normal workloads, you either need more RAM or to work on reducing your memory consumption; swapping is for temporary overloads or gracefully recovering from one, not a substitute for RAM.

It's not -- I'm getting OOM on some java processes and my swappiness is set to 60.

Java has its own memory limits that it will trigger OOMs at.
