It should be installed in the host, the container is using the same
kernel as the host. I'll kick off a build for trusty.

I have a fix, but I will want to run it by upstream before we apply it
to be sure we aren't opening up any security issues. In the meantime
I've put up a test build, please give it a try and verify that the uuid-
runtime upgrade can be successfully installed.
Seth, is this for the host or the container? Either way, I'm not running
4.2..

I've seen this pretty consistently too across a few hundred containers.
My guess so far was that it had to do with filesystem capabilities or
something similar.
So things are set properly when the image is unpacked by real root on
the host, but the extended attribute then can't be modified from
Marking confirmed based on stgraber's comment.

You can work around this by doing
echo 0 | sudo tee -a /proc/sys/fs/protected_hardlinks

Yes, seems to be a broken filesystem. What type of filesystem is this?
Check dmesg/syslog for errors. Also can you touch somenewfile in that
directory?
Unless... do you have SELinux enabled or something?

That sounds a bit like fs corruption then. Can you please do
cd /usr/bin; sudo strace -fvvs1024 -o /tmp/trace ln uuidd uuidd.bak
and attach /tmp/trace? I guess it really fails in link(2) with EPERM
("old name is a directory") or EACCESS ("new path directory is not
writable"), but let's make
