3417 C<guestfs_mkmountpoint> and C<guestfs_rmmountpoint> are
3418 specialized calls that can be used to create extra mountpoints
3419 before mounting the first filesystem.
3421 These calls are I<only> necessary in some very limited circumstances,
3422 mainly the case where you want to mount a mix of unrelated and/or
3423 read-only filesystems together.
3425 For example, live CDs often contain a \"Russian doll\" nest of
3426 filesystems, an ISO outer layer, with a squashfs image inside, with
3427 an ext2/3 image inside that. You can unpack this as follows
3430 add-ro Fedora-11-i686-Live.iso
3434 mkmountpoint /ext3fs
3436 mount-loop /cd/LiveOS/squashfs.img /sqsh
3437 mount-loop /sqsh/LiveOS/ext3fs.img /ext3fs
3439 The inner filesystem is now unpacked under the /ext3fs mountpoint.
3441 C<guestfs_mkmountpoint> is not compatible with C<guestfs_umount_all>.
3442 You may get unexpected errors if you try to mix these calls. It is
3443 safest to manually unmount filesystems and remove mountpoints after use.
3445 C<guestfs_umount_all> unmounts filesystems by sorting the paths
3446 longest first, so for this to work for manual mountpoints, you
3447 must ensure that the innermost mountpoints have the longest
3448 pathnames, as in the example code above.

3758 The inotify subsystem can be used to notify events which happen to

3766 Beyond this limit, the kernel throws away events, but records
3767 the fact that it threw them away by setting a flag
3768 C<IN_Q_OVERFLOW> in the returned structure list (see
3769 C<guestfs_inotify_read>).

4055 the underlying filesystem is case-insensitive, the driver

4149 This command creates a directory, setting the initial permissions
4150 of the directory to C<mode>.
4152 For common Linux filesystems, the actual mode which is set will
4153 be C<mode & ~umask & 01777>. Non-native-Linux filesystems may
4154 interpret the mode in other ways.

4158 ("lchown", (RErr, [Int "owner"; Int "group"; Pathname "path"], []), 203, [],
4160 "change file owner and group",
4162 Change the file owner to C<owner> and group to C<group>.
4163 This is like C<guestfs_chown> but if C<path> is a symlink then
4164 the link itself is changed, not the target.
4166 Only numeric uid and gid are supported. If you want to use
4167 names, you will need to locate and parse the password file
4168 yourself (Augeas support makes this relatively easy).");
4170 ("lstatlist", (RStructList ("statbufs", "stat"), [Pathname "path"; StringList "names"], []), 204, [],
4172 "lstat on multiple files",
4174 This call allows you to perform the C<guestfs_lstat> operation
4175 on multiple files, where all files are in the directory C<path>.
4176 C<names> is the list of files from this directory.
4178 On return you get a list of stat structs, with a one-to-one
4179 correspondence to the C<names> list. If any name did not exist
4180 or could not be lstat'd, then the C<ino> field of that structure
4183 This call is intended for programs that want to efficiently
4184 list a directory contents without making many round-trips.
4185 See also C<guestfs_lxattrlist> for a similarly efficient call
4186 for getting extended attributes. Very long directory listings
4187 might cause the protocol message size to be exceeded, causing
4188 this call to fail. The caller must split up such requests
4189 into smaller groups of names.");
4191 ("lxattrlist", (RStructList ("xattrs", "xattr"), [Pathname "path"; StringList "names"], []), 205, [Optional "linuxxattrs"],
4193 "lgetxattr on multiple files",
4195 This call allows you to get the extended attributes
4196 of multiple files, where all files are in the directory C<path>.
4197 C<names> is the list of files from this directory.
4199 On return you get a flat list of xattr structs which must be
4200 interpreted sequentially. The first xattr struct always has a zero-length
4201 C<attrname>. C<attrval> in this struct is zero-length
4202 to indicate there was an error doing C<lgetxattr> for this
4203 file, I<or> is a C string which is a decimal number
4204 (the number of following attributes for this file, which could
4205 be C<\"0\">). Then after the first xattr struct are the
4206 zero or more attributes for the first named file.
4207 This repeats for the second and subsequent files.
4209 This call is intended for programs that want to efficiently
4210 list a directory contents without making many round-trips.
4211 See also C<guestfs_lstatlist> for a similarly efficient call
4212 for getting standard stats. Very long directory listings
4213 might cause the protocol message size to be exceeded, causing
4214 this call to fail. The caller must split up such requests
