The findmnt command from util-linux only displays /dev/pts when run on a Ubuntu Truty install using the 3.16 Utopic kernel:

$ findmnt
TARGET SOURCE FSTYPE OPTIONS
/dev/pts devpts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000

This is true on both fresh Ubuntu 14.04.2 installs as well as Ubuntu 14.04.1 installs with the kernel upgraded to 'linux-generic-lts-utopic'. The same command works correctly on a fresh Ubuntu 14.04.1 install with the original 3.13 kernel. Also, the command seems to work correctly in the Ubuntu 14.04.2 liveboot environment, but not after rebooting into a fresh Ubuntu 14.04.2 install.

According to the discussion in the comments at http://lwn.net/Articles/634263/, this seems to be a known bug in util-linux due to a 3.14 kernel chnage. The util-linux bug has been fixed upstream:

http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/8557/focus=8558
https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=6c373810f5b1d32824371e9dff6ee5a006388f98

The updated version of util-linux, however, is not available in the Trusty repos.

Can we get the upstream fix backported into the Trusty-version of util-linux? Or better yet, should there be a 'util-linux-lts-utopic' package that tracks the newer versions of util-linux matched to the newer LTS kernel versions? It seems that as long as Ubuntu is going to supply LTS Enablement Stack kernels, it also needs to supply LTS-variants of packages that closely track the kernel like util-linux. Other examples of similar scenarios also come to mind (e.g. btrfs-tools, etc).
