FUSE filesystem support.

This implements FUSE filesystem support so that any libguestfs-
accessible disk image can be mounted as a local filesystem.

Note: file writes (ie. write(2) system call) is not yet implemented.

The API needs more test coverage, particularly lesser-used system
calls.

The big unresolved issue is UID/GID mapping between guest filesystem
IDs and the host.  It's not easy to automate this because you need
extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).

FTP server or FUSE?
-------------------
FUSE API
--------
Originally we had intended to implement an NFS server inside the
appliance, which would allow the guest filesystems to be mounted on
the host, and large changes to be made. We eventually rejected the
idea of using NFS, partly because it requires root to mount
filesystems in the host, and partly because of problems handling UID
mappings between host and guest filesystem.
The API needs more test coverage, particularly lesser-used system
calls.
Then we look at implementing an FTP server instead. FTP clients are
widely available for many languages, don't require root, and don't
have any UID mapping problems. However there is the problem of
getting the TCP connection into the guest, and that FTP requires a
secondary data connection either in or out of the guest (the NFS
situation is even more dire).
Thirdly we looked at implementing a FUSE-based filesystem. This is
plausible - it could be implemented just by adding the additional FUSE
operations to the standard guestfs(3) API, and then implementing a
simple FUSE daemon. (The FUSE website has some very helpful
documentation and examples). I [RWMJ] am not particularly convinced
that a FUSE-based filesystem would really be useful to anyone, but am
prepared to accept patches if someone does all the work.
See also the mountlo project:
http://sourceforge.net/project/showfiles.php?group_id=121684&package_id=150116
The big unresolved issue is UID/GID mapping between guest filesystem
IDs and the host. It's not easy to automate this because you need
extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).

=head1 NAME
guestmount - Mount a guest filesystem on the host using FUSE and libguestfs
=head1 SYNOPSIS
guestmount [--options] -a disk.img -m device [--ro] mountpoint
=head1 WARNING
You must I<not> use C<guestmount> in read-write mode on live virtual
machines. If you do this, you risk disk corruption in the VM.
=head1 DESCRIPTION
The guestmount program can be used to mount virtual machine
filesystems and other disk images on the host. It uses libguestfs for
access to the guest filesystem, and FUSE (the "filesystem in
userspace") to make it appear as a mountable device.
Along with other options, you have to give at least one device (I<-a>
option) and at least one mountpoint (I<-m> option). How this works is
better explained in the L<guestfish(1)> manual page, or you can use
L<virt-inspector(1)> and/or the the wrapper script
C<guestmount-wrapper> to help you.
FUSE lets you mount filesystems as non-root. The mountpoint must be
owned by you, and the filesystem will not be visible to any other
users unless you make certain global configuration changes to
C</etc/fuse.conf>. To unmount the filesystem, use the C<fusermount -u>
command.
=head1 EXAMPLES
For a typical Windows guest which has its main filesystem on the
first partition:
guestmount -a windows.img -m /dev/sda1 --ro /mnt
For a typical Linux guest which has a /boot filesystem on the first
partition, and the root filesystem on a logical volume:
guestmount -a linux.img -m /dev/VG/LV -m /dev/sda1:/boot --ro /mnt
To get L<virt-inspector(1)> to do the hard work of detecting guest
mountpoints for you:
guestmount $(virt-inspector --ro-fish MyGuest) /mnt
(or use --fish if you don't want it to be a read only mount). The
option is called I<--ro-fish> or I<--fish> because these parameters
are compatible with L<guestfish(1)>.
If you want to trace the libguestfs calls but without excessive
debugging, we recommend:
guestmount [-a ... -m ...] --trace /mnt
If you want to debug the program, we recommend:
guestmount [-a ... -m ...] --trace --verbose /mnt
=head1 OPTIONS
=over 4
=item B<-a image> | B<--add image>
Add a block device or virtual machine image.
=item B<--dir-cache-timeout N>
Set the readdir cache timeout to I<N> seconds, the default being 60
seconds. The readdir cache [actually, there are several
semi-independent caches] is populated after a readdir(2) call with the
stat and extended attributes of the files in the directory, in
anticipation that they will be requested soon after.
There is also a different attribute cache implemented by FUSE
(see the FUSE option I<-o attr_timeout>), but the FUSE cache
does not anticipate future requests, only cache existing ones.
=item B<--fuse-help>
Display help on special FUSE options (see I<-o> below).
=item B<--help>
Display brief help and exit.
=item B<-m dev[:mnt]> | B<--mount dev[:mnt]>
Mount the named partition or logical volume on the given mountpoint
B<in the guest> (this has nothing to do with mountpoints in the host).
If the mountpoint is omitted, it defaults to C</>. You have to mount
something on C</>.
=item B<-n> | B<--no-sync>
By default, we attempt to sync the guest disk when the FUSE mountpoint
is unmounted. If you specify this option, then we don't attempt to
sync the disk. See the discussion of autosync in the L<guestfs(3)>
manpage.
=item B<-o option> | B<--option option>
Pass extra options to FUSE.
To get a list of all the extra options supported by FUSE, use the
command below. Note that only the FUSE I<-o> options can be passed,
and only some of them are a good idea.
guestmount --fuse-help
Some potentially useful FUSE options:
=over 4
=item B<-o allow_other>
Allow other users to see the filesystem.
=item B<-o attr_timeout=N>
Enable attribute caching by FUSE, and set the timeout to I<N> seconds.
=item B<-o kernel_cache>
Allow the kernel to cache files (reduces the number of reads
that have to go through the L<guestfs(3)> API). This is generally
a good idea if you can afford the extra memory usage.
=item B<-o uid=N> B<-o gid=N>
Use these options to map all UIDs and GIDs inside the guest filesystem
to the chosen values.
=back
=item B<-r> | B<--ro>
Add devices and mount everything read-only. Also disallow writes and
make the disk appear read-only to FUSE.
This is highly recommended if you are not going to edit the guest
disk. If the guest is running and this option is I<not> supplied,
then there is a strong risk of disk corruption in the guest. We try
to prevent this from happening, but it is not always possible.
=item B<--selinux>
Enable SELinux support for the guest.
=item B<--trace>
Trace libguestfs calls (to stderr).
This also stops the daemon from forking into the background.
=item B<-v> | B<--verbose>
Enable verbose messages from underlying libguestfs.
=item B<-V> | B<--version>
Display the program version and exit.
