I did not get solution 3 to work correctly. So I chose solution 2 (this
is also the scheme that is used by debian afaics). See:



I'm going to submit this to bugzilla as review request at the beginning
of next week if no one complains loudly. (side note: rpmlint does not
like it very much:

$ rpmlint rpmbuild/RPMS/i386/fuse-2.4.1-2.i386.rpm
W: fuse non-conffile-in-etc /etc/udev/rules.d/40-fuse.rules
W: fuse non-conffile-in-etc /etc/makedev.d/z-fuse
E: fuse non-standard-gid /usr/bin/fusermount fuse
E: fuse setuid-binary /usr/bin/fusermount root 04754
E: fuse non-standard-executable-perm /usr/bin/fusermount 04754
W: fuse non-conffile-in-etc /etc/udev/makedev.d/40-fuse.nodes

The fuse kernel-module is in the latest rawhide kernel or in this one
for FC4:

It is not in the 2.6.14 kernel currently in updates-testing for FC4 --
but the above kernel or a newer one afaik should hit updates-testing
before 2.6.14 is shipped as official update.
