archfs has been accepted into unstable! I've been working on this package in between other tasks for quite a long time. I based my package on prior packaging work by Adam Sloboda from mentors.debian.net. The upstream package lacks a manpage, and one of the changes I have made from the initial packaging was to replace an XML-authored manpage by Adam with a roff one (based on the processed output of the XML one).
I did this because I find authoring roff documents easier than XML ones. Another consequence is the build dependencies a lot simpler. We can see just how simpler thanks to Frans Pops' debtree.
