It would be handy to be able to say: all e* functions die, but do* and new* do not. But tommy's list shows that emake is an exception to the rule.

Regards, Petteri Looks like people have been truly over-zealous when removing "die" statements from ebuilds lately. I've added back to HAL an assortment of "die" statements. I hope this hasn't happened in too many other ebuilds.

Very nice edge case and great work tracking down the cause.

Although I mentioned just baselayout and openrc, I did check ( end reemerged etc) hal also, and it indeed emerged _without_ /etc/init.d/hald. I tracked it down to root cause: Although I don't use it, I have compiled-in selinux support ( and selinux=0 as kernel start parameter). When I was makeconfiging my kernel, I saw also SMACK support, read info and thought "what the heck, it can't hurt me, but I might want to play with it", so I compiled-in that, too. Then after some time I realised that I never got to actually used all that and changed my config file by cutting out that all that security stuff. And recompiled all my kernels accordingly. Around that time I saw people recommending using tmpfs for /var/tmp as this would speed-up emerges etc, so I did that. I didn't know that while I was on SMACK (pun intended) , machine would add extended attr to every file machine would write. ( It was SMACK64 in security domain ). After cleaning my system, even though those attributes were still on all files, everything was fine until I actually tried to copy something from that FS to some other FS. /bin/cp would realise that there are extra security attrs on a file and would try to duplicate them on a copy. And since new kernel was without SMACK support, it would fail. When emerging stuff with /var/tmp on tmpfs, /bin/cp seems to get rarely used in such way when copying stuff into /var/tmp or maybe it was because distfiles were without SMACK attrs- so most ebuilds would seemingly sucseed. Most errors seem tho have been made when ebuild needed some local data, usually in /etc that had SMACK64 attr. If /bin/cp was used to get that data, it would fail, but this would not stop the ebuild. It would usually finished its work just as if nothing happened. Once I unmounted /var/tmp, ebuild could finish normally. Also, after removing security attr from all files, ebuild has started working normally from tmpfs partition again. It is also interesting that on 2.6.27* kernel ebuild fails sometimes and when it fails, it does so silently most of the time. With newest 2.6.28-rc9 i couldn't emerge a thing... Since I might not be the only tinkerer on Gentoo to try stuff like that and since it took me a day to find this, maybe it wouldn't hurt to check for this kind of thing in portage ? At the very least failed cp should stop emerge...

FWIW, this would have been a perfect question for the gentoo-desktop list, but doesn't really belong on the -dev list. There's also the gentoo-user list, altho that one has very heavy volume so you might not wish to subscribe there. I know you didn't know where to post, so this is simply for future reference. Try to keep the -dev list for technical dev discussion, as every post the devs have to deal with here is time they can't be spending on fixing packages. =:^( > I was forced to switch baselayout from stable 1.12.11* to 2.0.0, which > triggered openrc install etc. I did all that etc , then after some time > I noticed that system doesn't respond to PnP events. > > So I started looking around and have noticed that I have no > /etc/init.d/hald and that hal daemon never gets called during boot. > Then I tried to find alternate hald starting mechanism, but couldn't > find any.

What version? The above hal-0.5.11-r4 is the ~arch version, but -r1 appears to be the latest stable (except for arm and sh, on which 0.5.9.1-r3 is latest stable) and at least my archived binpkg -r1 has /etc/init.d/hald as well. Even my oldest archived hal-0.5.10 binpkg has that file. So if it's not being created when you remerge hal and you aren't running something terribly outdated, I'd say it's time to look up hal bugs, and to file one if necessary.
