Click fails to create chroot (exit status 100) during Kit creation process

[Aaron Hastings]

Creating a Kit using the Ubuntu SDK startup wizard. Everything starts okay and packages begin to download and install, etc. All of a sudden the process stops and I get the following output in bold red text:

There was an error creating the click target, cleaning up
click target was removed successfully

Okay, turns out this is not a false reporting. My root filesystem turned out to be eating inodes, locking up my system just a few minutes later.

Still, I'll leave this here in case it presents any usability issues (e.g. better reporting that disk space is the cause).
