[Bug 1754777] Re: bionic casper nfsboot not reaching desktop env, failure to mount various kernel filesystems and /tmp

[Jeff Sereno]

Same issue here. Using a combo of the OP's and mabes' info, I was able
to successfully PXE boot using the following kernel line:

kernel path/to/tftp/bionic/vmlinuz systemd.mask=dev-hugepages.mount
systemd.mask=dev-mqueue.mount systemd.mask=sys-fs-fuse-connections.mount
systemd.mask=sys-kernel-config.mount systemd.mask=sys-kernel-debug.mount
systemd.mask=tmp.mount

I was unable to use just systemd.mask=tmp.mount alone as suggested by
mabes.

To get DNS going, I just changed the nameserver IP in /etc/resolv.conf
to 8.8.8.8 and I was good (I also have this particular issue under 17.10
when PXE booted).

Shutdown (and reboot) does NOT hang in my case.

Title:
  bionic casper nfsboot not reaching desktop env, failure to mount
  various kernel filesystems and /tmp

Status in casper package in Ubuntu:
  Confirmed

Bug description:
  1st of all, i am successfully using casper netboot with this distros:
    menu label   Ubuntu 13.10 "Saucy Salamander" - Release i386
    menu label   Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64
    menu label   Ubuntu 14.04.4 LTS "Trusty Tahr" - Release amd64
    menu label   Ubuntu 16.04.3 LTS "Xenial Xerus" - Release i386
  but not with
    menu label   Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64

  boot process gets to the point of running this services
    dev-hugepages.mount
    dev-mqueue.mount
    sys-fs-fuse-connections.mount
    sys-kernel-config.mount
    sys-kernel-debug.mount
    tmp.mount

  and it stops in emergency console.

  Too run further to gnome session i've need to do

  #systemctl mask dev-hugepages.mount
  #systemctl mask dev-mqueue.mount
  #systemctl mask sys-fs-fuse-connections.mount
  #systemctl mask sys-kernel-config.mount
  #systemctl mask sys-kernel-debug.mount
  #systemctl mask tmp.mount 
  #ctrl-d

  after this i get normal live session except wrong dns setting, which is fixed by setting my router's
  dns as resolver
  #echo "nameserver 192.168.1.1" > /etc/resolv.conf

  
  Please fix boot process.
