Objections?
I saw the thread on portage-dev so was waiting for the thread here that you mentioned you'd start... Some years ago I had some problem or other with the usersandbox and userpriv combination (AFAIK it would work with just one of the two, but not both), but that was several years ago now, and was almost certainly ~arch (and possibly pre-unmask), so yes, I'd say have them both on by default. I've had no problem with it recently. As is traditional for this sort of defaults-change, I'd suggest creating a news item for it, with the usual paragraph explanation and referral to the manpage and/or handbook for more information. If I don't miss my guess, there's likely a number of folks that had either userpriv or userstandbox disabled for some package or other, years ago, who simply forgot about it and never reenabled. I'm usually pretty good about that, and only probably 6-8 months ago realized I had one of the two disabled, and couldn't remember why (probably 2-3 years ago I started putting dated comments in the config when I did stuff like that, so whatever it was, was awhile back...), so it had obviously been disabled for awhile. (I've done at least one and I think two full emerge --emptytree @worlds since then, however, so as I said above, everything that's installed now is fine.) A news item will help remind folks with older installs to check their status as well, which can only be a good thing. =:^) So from this user, +1 (+1000? =:^), news item requested. =:^) -- Duncan - List replies preferred.
