The intended purpose of this task is to run checks on the contents of
the image before it's booted.

I implemented a similar task in meta-swupd to run various checks such
as ensuring a generated image doesn't contain dangling symlinks (a sign
of unexpected consequences from alternatives configuration).

Another check one might run is ensuring /etc and /var are empty in a
stateless distro, or checking /bin, /lib and /sbin are links in a
distro with a merged /usr.

When I have a v2 of this which addresses some of Chris' concerns I'll
try and improve the commit message, variable naming, etc to avoid
confusion.

Joshua
