Subject: [PATCH 0/2] e2fsprogs: fuse2fs bugfix and new 'fakeroot' feature

From: Nick Clark <nicholas.clark@...il.com>

Hi all,

I wrote a couple of patches for fuse2fs (from the e2fsprogs collection).
One is a minor bugfix to the displayed name in the mount command's output,
and the other is a new 'fakeroot' mount option, as described below.

When building cross-compiled Linux systems (for use on routers, consumer
devices, etc), it's often necessary to build rootfs filesystem images.
This commit adds a new 'fakeroot' mount option that gives a user full
control over the mounted filesystem, within the confines of FUSE.

When used, the new option allows treats allowed users as uid 0 for the
purposes of permission checks (within the mounted filesystem). This
allows the owner of a .img file to mount the file and make whatever
changes they want to any files inside of the image.

If the option is left disabled at mount-time, fuse2fs acts the same as
before - only root can edit "root"-owned files inside of the image. But
when enabled, fuse2fs becomes a powerful tool to build/modify filesystem
images.

What do you all think?

  Fuse2fs: fix 'mount' entry in some cases.
  Fuse2fs: add fakeroot option.
