checkupdates feature request: "rm -rf $CHECKUPDATES_DB" on script exit
It's a waste of resources to keep CHECKUPDATES_DB
in a lot of cases.
Locking the deleting or current behavior behind an option would suffice, the former provides backwards-compatibility; I prefer default-deleting, as this is suited for my use-case.
I am willing to provide help, or even write this myself; I do not have much, if any, experience with bash-scripts.
