Plugins are simply provided as a shared image in e.g.
/usr/lib/ext2fs/fsimage.so. Originally I was planning on using the "call
a binary" approach, but Jeremy was very unhappy with that, and it is
somewhat more awkward for searching for grub's config file, etc.

But a vendor can easily provide whatever 'fsimage.so' they feel is more
appropriate.

Simply put, I have no idea how to get Linux distributions to integrate
libfsimage into their packages, otherwise I'd just do that.
