I don't see any concrete advantages listed (either for upstart, or for the alternatives listed by others).
From memory, I think the reason ubuntu moved from sysvinit was to speed up their boot process. Last time I used ubuntu (admittedly a long time ago), my impression was that their boot process was excessively complex, and in some ways I would actually describe it as "wrong" (like debian, run a graphical login on all runlevels for desktops). I also recall that they switched to dash, which I regard as an *inadequate* shell, to improve their boot times. Do I think the LFS/BLFS desktop boot could be quicker ? Of course. In my case, I get a delay of several seconds while ntp starts up. But so far, I've managed to live with that and I know that it *doesn't* need a completely revised method of booting to address it. I might be misjudging you, but so far your post comes across as "ooh, upstart is newer and shinier". ISTR those were the motivations behind kde4 - and for those of us who build from source on bare metal, that turned into a disaster (total bloat). I suggest that you identify *what* you think can be done better during the boot process, then go off and try different method(s) - if any of them provides a significant benefit, come back and explain why you think the change is worthwhile - if the aim is to speed up the boot, timings will be useful. In my case, the slowest part of booting my desktop machines is waiting for the bios to present me with the grub boot screen, then the ntp delay I mentioned. From memory, I think that saving 5 seconds in the whole process is actually neither here nor there, but people have different views. ĸen -- After tragedy, and farce, "OMG poneys!" -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
