I will not be supporting a systemd system with an mkinitrd initrd. + +This is because systemd is fully hotplug, and thus does not just "try +and do things" and hope for the best. It waits until it knows devices +are available before using them. It does this via udev. If anything +mildly exotic is used (e.g. LVM, RAID etc.) then it is the initrd's job +to start these. If it's done in an mkinitrd, the metadata generated from +activating these devices is lost as udev is not running at the time. In +dracut, udev is running and critical metadata is saved and preserved for +systemd to use later. + +So, with the background of why I will not support systemd+mkinitrd out +of the way, we have to look at the kernels themselves. We require dracut +now, but it's still perfectly possible to install mkinitrd and set the +alternatives up correctly such that it is used (update-alternatives +--display mkinitrd). If you do this, you are on your own - you need to +remember to install sysvinit and not let systemd be your init. + + + +The original question is "why does the kernel require dracut?" Well, +it's our preferred initrd but, as mentioned above, you can still use +mkinitrd if you absolutely must, but you have to know the consequences +and repercussions. I originally made dracut fully obsolete mkinitrd, +giving no choice in the matter. This is still my preferred option for +mga2 if at all possible, but as I believe others want to keep it for +now, I'm fine with it. The kernel requires dracut to make sure that the +default init system (systemd) and the kernel initrd (made with dracut) +are paired. + +Hope that answers your question. + +Col + + + +-- + +Colin Guthrie +colin(at)mageia.org +<A HREF="http://colin.guthr.ie/">http://colin.guthr.ie/</A> + +Day Job: + Tribalogic Limited <A HREF="http://www.tribalogic.net/">http://www.tribalogic.net/</A> +Open Source: + Mageia Contributor <A HREF="http://www.mageia.org/">http://www.mageia.org/</A> + PulseAudio Hacker <A HREF="http://www.pulseaudio.org/">http://www.pulseaudio.org/</A> + Trac Hacker <A HREF="http://trac.edgewall.org/">http://trac.edgewall.org/</A> +</PRE> + + + + + + + + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="011580.html">[Mageia-dev] mkinitrd and Mageia2 +</A></li> + <LI>Next message: <A HREF="011588.html">[Mageia-dev] mkinitrd and Mageia2 +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#11583">[ date ]</a> + <a href="thread.html#11583">[ thread ]</a> + <a href="subject.html#11583">[ subject ]</a> + <a href="author.html#11583">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> -- cgit v1.2.1
