Based on the man page you sent, the live booting involves the transfer of an image from the server to the client... but we don't want to transfer any image... I need it to be a rootnfs. Please correct me if I missed the option that allows for a live system + overlay over nfs. Thank you. ________________________________ From: David Cassany <dcassany@xxxxxxx> Sent: Wednesday, October 30, 2019 7:18:03 AM To: initramfs@xxxxxxxxxxxxxxx Cc: Matteo Guglielmi Subject: Re: rootnfs + dracut overlay (diskless client shutdown issue) Hi, I am not really a dracut expert but a dracut user.

I'd say this is likely to be the problem. overlay-root is not part of dracut upstream and overly-root module seams to be Debian specific. I doubt it can work with CentOS out of the box. It might not be cross distro. In order have a good systemd integration I'd say you should use sysroot.mount generator and I didn't see any in 90overlay-root. Note that since dracut v049 the livenet module supports overlay, I believe this might be an easier setup. See http://man7.org/linux/man-pages/man7/dracut.cmdline.7.html live booting section for the parameters and configuration. Again, just my 2 cents, I am not a dracut expert. Regards, David
