[Bug 1755863] Re: netbooting the bionic live CD over NFS goes straight to maintenance mode :

[beta-tester]

@Eric,
i just tested what you suggested at your comment #31 with Ubuntu 18.10 release ...
    KERNEL http://pxe-server/nfs/ubuntu-x64/casper/vmlinuz
    INITRD http://pxe-server/nfs/ubuntu-x64/casper/initrd
    APPEND nfsroot=192.168.1.1:/srv/nfs/ubuntu-x64 ro netboot=nfs file=/cdrom/preseed/ubuntu.seed boot=casper systemd.mask=dev-hugepages.mount -- debian-installer/language=de console-setup/layoutcode=de keyboard-configuration/layoutcode=de keyboard-configuration/variant=German

... but then i again run straight into emergency console.
(not sure, if that information still is helpful)

at the moment "systemd.mask=tmp.mount" still is the best solution.
but with the issues of:
- having few red "FAILED" messages at boot time;
- at reboot/poweroff often run into "stop jobs" are running endless at shutting down;
- or hangs for ever at "Starting Shuts down the 'live' preinstalled system clearly...";

the second best solution is "toram", there i never observed the issues of any "FAILED" message and never hat the issues at reboot/poweroff (maybe there are race conditions - "toram" nothing has to be loaded fron nfs via network).
but "toram" takes a lot of time, because the whole squashfs-image has to be loaded into ram first, before it can be mounted.

BTW: lununtu 18.10 shows the same behavior as ubuntu 18.10, but it does
not show up the issues with reboot/poweroff hanging or endles running
stop jobs.
