+
+This adds a drive in snapshot mode, making it effectively
+read-only.
+
+Note that writes to the device are allowed, and will be seen for
+the duration of the guestfs handle, but they are written
+to a temporary file which is discarded as soon as the guestfs
+handle is closed. We don't currently have any method to enable
+changes to be committed, although qemu can support this.

=head2 aug-close
The single parameter is an argv-style list of arguments.
The first element is the name of the program to run.
Subsequent elements are parameters. The list must be
-non-empty (ie. must contain a program name).
+non-empty (ie. must contain a program name). Note that
+the command runs directly, and is I<not> invoked via
+the shell (see C<sh>).
The return value is anything printed to I<stdout> by
the command.
This is the same as C<command>, but splits the
result into a list of lines.
+See also: C<sh-lines>
+
Because of the message protocol, there is a transfer limit
of somewhere between 2MB and 4MB. To transfer large files you should use
FTP.
This returns the verbose messages flag.
+=head2 glob-expand
+
+ glob-expand pattern
+
+This command searches for all the pathnames matching
+C<pattern> according to the wildcard expansion rules
+used by the shell.
+
+If no paths match, then this returns an empty list
+(note: not an error).
+
+It is just a wrapper around the C L<glob(3)> function
+with flags C<GLOB_MARK|GLOB_BRACE>.
+See that manual page for more details.
+
=head2 grub-install
grub-install root device
Create a directory named C<path>, creating any parent directories
as necessary. This is like the C<mkdir -p> shell command.
+=head2 mkdtemp
+
+ mkdtemp template
+
+This command creates a temporary directory. The
+C<template> parameter should be a full pathname for the
+temporary directory name with the final six characters being
+"XXXXXX".
+
+For example: "/tmp/myprogXXXXXX" or "/Temp/myprogXXXXXX",
+the second one being suitable for Windows filesystems.
+
+The name of the temporary directory that was created
+is returned.
+
+The temporary directory is created with mode 0700
+and is owned by root.
+
+The caller is responsible for deleting the temporary
+directory and its contents after use.
+
+See also: L<mkdtemp(3)>

=head2 mkfs
mkfs fstype device
This moves a file from C<src> to C<dest> where C<dest> is
either a destination filename or destination directory.
+=head2 ntfs-3g-probe
+
+ ntfs-3g-probe true|false device
+
+This command runs the L<ntfs-3g.probe(8)> command which probes
+an NTFS C<device> for mountability. (Not all NTFS volumes can
+be mounted read-write, and some cannot be mounted at all).
+
+C<rw> is a boolean flag. Set it to true if you want to test
+if the volume can be mounted read-write. Set it to false if
+you want to test if the volume can be mounted read-only.
+
+The return value is an integer which C<0> if the operation
+would succeed, or some non-zero value documented in the
+L<ntfs-3g.probe(8)> manual page.

=head2 ping-daemon

Remove the single directory C<path>.
+=head2 scrub-device
+
+ scrub-device device
+
+This command writes patterns over C<device> to make data retrieval
+more difficult.
+
+It is an interface to the L<scrub(1)> program. See that
+manual page for more details.
+
+B<This command is dangerous. Without careful use you
+can easily destroy all your data>.
+
+=head2 scrub-file
+
+ scrub-file file
+
+This command writes patterns over a file to make data retrieval
+more difficult.
+
+The file is I<removed> after scrubbing.
+
+It is an interface to the L<scrub(1)> program. See that
+manual page for more details.
+
+=head2 scrub-freespace
+
+ scrub-freespace dir
+
+This command creates the directory C<dir> and then fills it
+with files until the filesystem is full, and scrubs the files
+as for C<scrub-file>, and deletes them.
+The intention is to scrub any free space on the partition
+containing C<dir>.
+
+It is an interface to the L<scrub(1)> program. See that
+manual page for more details.

=head2 set-append | append
set-append append
human-readable output of the L<sfdisk(8)> command. It is
not intended to be parsed.
+=head2 sh
+
+ sh command
+
+This call runs a command from the guest filesystem via the
+guest's C</bin/sh>.
+
+This is like C<command>, but passes the command to:
+
+ /bin/sh -c "command"
+
+Depending on the guest's shell, this usually results in
+wildcards being expanded, shell expressions being interpolated
+and so on.
+
+All the provisos about C<command> apply to this call.
+
+=head2 sh-lines
+
+ sh-lines command
+
+This is the same as C<sh>, but splits the result
+into a list of lines.
+
+See also: C<command-lines>

+=head2 sleep
+
+ sleep secs
+
+Sleep for C<secs> seconds.
