old/cruft branch cleanup needed wrt importds

[Steve McInerney]

The server that the importd slaves write to is getting a tad on the full size.
It appears we have all sorts of old, possibly even ancient cruft that could be removed.

12Gb .db files don't help.

To open discussion:
Would be looking for a method - prefer automated, but wouldn't have to be - to be able to go through the various files/directories on the written-to server and remove those files/directories that are no longer relevant.
* perhaps a cron on a sole importd slave that could query and delete as necessary
* a report generated "somewhere" that webops staff could run; if these exist, leave alone; if something isn't in that list, remove.

We should no longer be generating .db files on escudero - the code imports now store their caches in a tarball and/or in the cache directory on the individual import slaves.

Is the size of the combined .tar.gz files a problem?

> Is the size of the combined .tar.gz files a problem?

yes and no. Yes in that they do keep growing; so having some method of cleaning the old no longer valid cruft is useful.
No in that we can always add more disk.

Ideally we want the two somewhat in balance; so we're not just blindly adding disk.
