I'm feeling lazy...

My /var/cache/distfiles just hit 100G; has anyone written a script to delete "old sources" once a newer version is downloaded?
Obviously I could just rm -rf it and deal with the problem in 4 years time, but I thought I'd ask first...

app-portage/gentoolkit provides eclean-dist command, which can precisely do this.

The --deep option allows to only keep files corresponding to currently installed packages.

I do it manually once in a while but you could automate it with a systemd service/timer / crontab, a simple bash script or even a Portage post-sync hook.

Thanks!
Now I'm glad I was feeling lazy, and didn't re-invent the wheel
