The primary purpose of this PR is to add DragonFlyBSD support. Note that it was tested with the HAMMER2 filesystem, I'm not sure if it works with a standard UFS filesystem, but it appears to be the default so I went with it.
I also updated the
umount
method, which now assumes that theumount2
function is defined on Linux systems. This simplified the implementation of the corresponding Ruby method.Last, I decided to finally remove Solaris support. It's dead.
