[Mageia-dev] ANN: Dracut now mounts /usr properly \o/

Thu Dec 15 23:14:54 CET 2011

OK, so this took me a while to actually get around to setting up some
+VMs to test this. Sorry about that :s
+
+Anyway, I've tested with a / on ext4 + /usr on LVM + ext4.
+
+With appropriate fixes, I was able to generate an initrd without any
+specific config to tell dracut what to do. There is a caveat. /usr is
+mounted read only. I can tweak this, but by the same token I'm not sure
+I should... It's trivial to do a "mount -o remount,rw /usr" if you want
+to install packages etc. Otherwise, /usr should pretty much be read only
+anyway.. if something tries to modify stuff on /usr that's not part of a
+package installation process that is (IMO) a bug and should be fixed.
+
+The code for mounting /usr is not the same as how it'll (eventually) be
+done upstream. It only deals with /usr and if you have e.g. /usr/bin on
+a separate partition they you are SOL and will have to wait for the
+upstream version.
+
+I think however that for the majority of setups the current solutions is
+likely good enough.
+
+
+Now, when I installed, dracut wasn't used as initrd, so if no one shouts
+too loudly I'll make it deprecate mkinitrd tomorrow and we can test
+installs where dracut generates the first initrd and see how it fairs.
+
+Please test and let me know. It's version 014.1mga2
