I've been thinking along the lines of a cronjob being pulled in with, |
| 15 |
say, Portage. Said cron job would, on a daily/weekly basis remove old |
| 16 |
distfiles based upon age, and perhaps even have a setting to consider |
| 17 |
size. (Eg; always/never remove files greater/less than a certain size). |
| 18 |

That's where it gets tricky. OpenOffice, Mozilla et al. are two great |
| 20 |
examples of packages whose source tarballs are *LARGE*. On one hand, |
| 21 |
those would, in one fell swoop, free up the most HDD space = most |
| 22 |
benefeit. On the other hand, they'd also cost more bandwidth to |
| 23 |
re-download = most detrimental. |
| 24 |
|
| 25 |
Operating on a strictly age-based system based around file access time |
| 26 |
could potentially work, except that Gentoo's install defaults and/or |
| 27 |
suggests strongly the notion of 'noatime' in fstab entries. |
| 28 |

The script for the cronjob is easy, especially if it's only date-based. |
| 30 |
The politics involved in implementing it, however, could be hairy. I'll |
| 31 |
throw my script out there for review if it interests anybody and let |
| 32 |
someone who's more proficient in Bash scripting add in the filesize details. |
