I have bloated my system with unnecessary packages and want to "start from zero". Rather than reinstalling I would prefer to do it from the OS and do it live.

How do I remove all packages not in base install?

Some relevant things that didn't quite pan out https://ask.fedoraproject.org/en/question/8646/erase-all-packages-except-a-given-list-of-packagesgroups/ https://wiki.archlinux.org/index.php/Pacman_tips#Removing_everything_but_base_group

Edit: to clarify using dnf

  • Most useful thing I have found so far is rpmreaper. Really useful for cleaning up so far. – Fabián Heredia Montiel May 19 '15 at 19:48

If you still have the original /root/install.log you can follow this answer to compare the originally-installed and subsequently-installed packages. If not, you will need to pull a list of base packages off your install-media and perform a similar comparison.

    another option is using ' /root/anaconda-ks.cfg ' it has the "'Groups" and any single packages installed at initial you can run rpm list installed |grep -v $(all those groups /packages) which gives you a naked initial install – linuxdev2013 May 12 '15 at 4:39
  • Ok, so second part of you answer, javabrett, was the one that helped, thanks. C: – Fabián Heredia Montiel May 19 '15 at 19:50
