Subject: findmnt on 3.14-rc3 – only shows /proc in tree mode
Date: Thu, 20 Feb 2014 15:43:13 +0200 [thread overview]
Message-ID: <le50p4$1td$1@ger.gmane.org> (raw)

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.

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
