will the Ubuntu 18.04 LTS (Bionic Beaver) receive that fix in the next point release as well? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1755863 Title: netbooting the bionic live CD over NFS goes straight to maintenance mode : Status in systemd: Unknown Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: In Progress Status in systemd source package in Bionic: In Progress Status in systemd source package in Cosmic: In Progress Status in systemd source package in Disco: Fix Released Bug description: [Impact] Mounting manually a network share (NFS) and masking it breaks the state of other units (and their dependencies). Casper is masking a mounted NFS share, blocking the normal boot process as described in the original description, but the issue comes from systemd.

Originally, one failing mount point blocked the processing of the rest due to how the return codes were handled for every line in /proc/self/mountinfo. This patch removes this "dependency" and keeps the failure local to the affected mount point, allowing the rest to be processed normally.
