[Mageia-dev] udev in initrd and/or using dracut (LVM root fs related)

Wed Oct 19 15:20:35 CEST 2011

Hi,
+
+In testing a more extensive use of systemd (i.e. using it to mount
+filesystems etc. rather than using rc.sysinit) I've run into a few
+problems regarding the fact that my LVM is activated in the initrd.
+
+Due to this, various entries in the udev db are not set. systemd uses
+these missing bits to launch the local-fs.target and thus fails (even if
+it's just my /home that is broken which won't really be needed).
+
+I've been told in various discussions with upstream that ultimately we
+need to use udev in the initrd. It seems that fedora and suse at least
+do this.
+
+I can work around it of course (we do so just now) but I'd like to get
+things working as "natively" as possible with systemd if possible.
+
+So should we:
+
+ a) Try to incorporate udev into our mkinitrd?
+ b) Switch to dracut
+
+I'm not an expert at this stuff, but I know that Mandriva has started
+using dracut more and I think it's likely the best solution overall
+seeing as it's Fedora's preferred mechanism too.
+
+But I didn't want to start looking at it until there is some consensus
+on this - hence this email.
+
+
+FWIW, I've put some detailed info on an Mdv bug concerning this same
+issue here:
+https://qa.mandriva.com/show_bug.cgi?id=63471

+
+PS I've CC'ed a couple of specifically interested/clued up people so
+they don't miss this mail, but of course comments from anyone are
+appreciated:)
