Using util-linux 2.24.1 on Arch Linux, running `findmnt` only shows mounts at or under "/proc", and ignores all other mount points (including "/"). This only happens in "tree" mode – if I run `findmnt --raw` it lists all mounts correctly. This happens with custom-built 3.14-rc3 kernel, but works fine with Arch's stock 3.13.x (the same Arch initramfs for both). Building `findmnt` from util-linux.git did not change anything. > $ findmnt > TARGET SOURCE FSTYPE OPTIONS > /proc proc proc rw,nosuid,nodev,noexec,relatime > └─/proc/sys/fs/binfmt_misc systemd-1 autofs rw,relatime,fd=21,pgrp=1,timeout=300,minprot > └─/proc/sys/fs/binfmt_misc binfmt_misc binfmt_mi rw,relatime It seems there is a small difference in /proc/self/mountinfo with 3.14; the entry for / looks like this: > 19 0 8:3 / / rw,relatime - ext4 /dev/sda3 rw,data=ordered ...while in 3.13 it used to be: > 19 1 8:3 / / rw,relatime - ext4 /dev/sda3 rw,data=ordered -- Mantas Mikulėnas <grawity@xxxxxxxxx>
