It can be an annoyance to need root for some things. This allows squashfs (XZ or zlib) mounts in user-space.
It seems to originate from bsd-land and has bsd licence (not gpl but similar) https://github.com/vasi/squashfuse
I built a deb (wheezy/sid) and posted here: http://exegnulinux.net/refracta/experim ... 1_i386.deb
Deps (all in wheezy): libc6 (>= 2.1), libfuse2 (>= 2.8.1), liblzma5 (>= 5.1.1alpha+20110809), zlib1g (>= 1:1.1.4)
It works, however if anyone is interested and knows more than me about deb-packaging, could use some help with two "lintian" errors.
