bindfs - http://code.google.com/p/bindfs/
3+
4+
-- Overview --
5+
6+
bindfs is a FUSE filesystem for mirroring a directory to another
7+
directory, similarly to mount --bind. The permissions of the mirrored
8+
directory can be altered in various ways.
9+
10+
Some things bindfs can be used for:
11+
- Making a directory read-only.
12+
- Making all executables non-executable.
13+
- Sharing a directory with a list of users (or groups).
14+
- Modifying permission bits using rules with chmod-like syntax.
15+
- Changing the permissions with which files are created.
16+
17+
Non-root users can use almost all features, but most interesting
18+
use-cases need user_allow_other to be defined in /etc/fuse.conf
19+
20+
21+
-- Installation --
22+
23+
Make sure fuse 2.5.3 or above is installed (http://fuse.sf.net/).
24+
Then compile and install as usual:
25+
./configure
26+
make
27+
make install
28+
29+
If you want the mounts made by non-root users to be visible to other users,
30+
you may have to add the line user_allow_other to /etc/fuse.conf.
31+
32+
33+
-- Usage --
34+
35+
See the bindfs --help or the man-page for instructions and examples.
36+
37+
38+
-- License --
39+
40+
GNU General Public License version 2 or any later version.
41+
See the file COPYING.

Major (i.e. probably not very soon):
3+
4+
- Applying options to a subset of all files;
5+
something like --if-file-matches '*.md5' { -u checksummer -p u+rw }
6+
- This would make for some new useful options like --hide or --deny
7+
- We could also have special xattrs like 'bindfs:perms' that
8+
don't get propagated to the base directory but control bindfs behaviour
9+
instead.
10+
- All this leads to the thought of an integrated minilanguage.
11+
Taken to the extreme, would this make bindfs almost yet another scripting
12+
language binding for FUSE?
13+
- Stackable/pluggable scripts? Any benefit over a remount?
14+
15+
Minor:
16+
17+
- Decide what to do with the fuse options uid=N and gid=N, or at least
18+
mention them in the docs.
19+
20+
- Look at capabilities instead of uid==0 when checking for special privileges.
21+
Do this in a portable way and fall back to uid==0 if not available.
