I'm proud to announce a new version of my pet project 'mountlo', a
utility which works similarly to 'mount -o loop', but the filesystem
runs entirely in userspace.
While arguably it is quite useless, I like it because it combines some
of my favorite technologies (Linux, UML and FUSE) with very little
additional glue code.
Features:
o safe mounting of filesystem images for unprivileged users
o all disk-filesystem types supported in a single binary
What's new since 0.2:
o support for partitioned disk images
o support for mount options
o error reporting both from mount and the kernel
o achieves reasonable performance using SKAS0 mode of UML
o verbose and debug modes
An i386 binary (2MB) is available at:
http://prdownloads.sourceforge.net/fuse/mountlo-i386-0.5.tar.gz
Requirements for running the binary are:
- FUSE kernel module. Since 2.6.14, this is included in mainline
- FUSE utilities (at least version 2.2).
Compiling from source needs the following components:
- http://prdownloads.sourceforge.net/fuse/mountlo-0.5.tar.gz
- Linux-2.6.15 kernel source
- FUSE-2.5 or later devel package (or source installation)
Comments and bug reports are welcome.

Very cute. I'm in the process of doing something similar, except I'm
integrating a FUSE server into the UML kernel to export the UML
filesystem to the host. So far, I can cd and ls inside the mount -
lookup and readdir are implemented.

Great. I always wanted to do the exporting inside the kernel, but put
it off as being too hard :)
