Hello all.. I'm trying to run CentOS 7 in a LXC container and need to disable udev so that we can manage the devices ourselves. I believe that I've disabled all of the systemd related udev services, but udev is still taking over and mounting /dev. What is the proper way to disable this? Thanks...Paul... -- --- Paul B Schroeder <paul.schroeder "at" nimbix "dot"

...these errors: Mounting none on /dev failed. No such device. ... Gave up waiting for root device. ... Alert! Could not mount /dev/sda1 as root device. Dropping to a shell. After this I get a (initramfs) shell. I figured out that this is due to the fact that a 2.6.18 kernel doesn''t support devtmpfs, which is the /dev filesystem Lucid uses. Now I would like to compile a newer kernel and use it as dom0. However, I could not find Xen-patched kernels that might have devtmpfs support (version >= 2.6.32). What are the steps I should take to get, patch and install such a kernel as dom0 (rather th...

I've pushed this upstream already, since Fedora Rawhide doesn't work without this patch. I'm posting here for the benefit of other distros that might hit this problem. Rich.

https://bugzilla.redhat.com/show_bug.cgi?id=1165785 Since the --boot option is relatively new (added 2013-12), I suspect this will break older versions of systemd. However it should be fine for all currently supported versions of Fedora. Rich.
