Mergemaster: Question about temproot

[abefar]

So... I've been wondering about this for ages without ever getting a clear answer:

What should I do with /var/tmp/temproot when mergemaster asks me (before and after doing make installworld in single user mode)?
Is it best to leave it alone after every mergemaster run? Or should I delete it after the final mergemaster run after installworld? Or should I always delete it, after running both mergemaster -p and the final mergemaster?

Thanks in advance! :)

make cleanworld will clean it up.

make cleanworld will clean it up.

I see. So it's best to let mergemester leave it alone at all times?

That's what I do, yes.

I always remove it. It takes a few seconds to make a new one when it's needed, and it serves no other purpose than mergemaster.
