to be created. The support is based on mtree version 2.0, as used
in libarchive, but adds new features on top of it.
The current implementation is fully functional, but is envisioned
to grow at least the following additional features over time:
o Add support for the /include special command so that manifest
files can be constructed using includable fragments.
o Add support specifying a search path to locate content files.
o Content file filters: commands that provide file contents on
stdout.
The manifest file eliminates the need to first construct a tree
as root in order to create an image and allows images (releases)
to be created directly from object trees and/or source trees.

|
.Sh DESCRIPTION
|
|
The utility
|
|
.Nm
|
|
creates a file system image into
|
|
.Ar image-file
|
|
from the directory tree
|
|
.Ar directory
|
|
or from the mtree manifest
|
|
.Ar manifest .
|
|
No special devices or privileges are required to perform this task.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width flag
|
|
.It Fl B Ar byte-order
|
|
Set the byte order of the image to
|
|
.Ar byte-order .
|
|
Valid byte orders are
|
|
.Ql 4321 ,
|
|
.Ql big ,
|
|
or
|
|
.Ql be
|
|
for big endian, and
|
|
.Ql 1234 ,
|
|
.Ql little ,
|
|
or
|
|
.Ql le
|
|
for little endian.
|
|
Some file systems may have a fixed byte order; in those cases this
|
|
argument will be ignored.
|
|
.It Fl b Ar free-blocks
|
|
Ensure that a minimum of
|
|
.Ar free-blocks
|
|
free blocks exist in the image.
|
|
An optional
|
|
.Ql %
|
|
suffix may be provided to indicate that
|
|
.Ar free-blocks
|
|
indicates a percentage of the calculated image size.
|
|
.It Fl d Ar debug-mask
|
|
Enable various levels of debugging, depending upon which bits are
|
|
set in
|
|
.Ar debug-mask .
|
|
XXX: document these
|
|
.It Fl F Ar specfile
|
|
Use
|
|
.Ar specfile
|
|
as an
|
|
.Xr mtree 8
|
|
.Sq specfile
|
|
specification.
|
|
This option has no effect when the image is created from a mtree manifest
|
|
rather than a directory.
|
|
.Pp
|
|
If a specfile entry exists in the underlying file system, its
|
|
permissions and modification time will be used unless specifically
|
|
overridden by the specfile.
|
|
An error will be raised if the type of entry in the specfile
|
|
conflicts with that of an existing entry.
|
|
.Pp
|
|
In the opposite case (where a specfile entry does not have an entry
|
|
in the underlying file system) the following occurs:
|
|
If the specfile entry is marked
|
|
.Sy optional ,
|
|
the specfile entry is ignored.
|
|
Otherwise, the entry will be created in the image, and it is
|
|
necessary to specify at least the following parameters in the
|
|
specfile:
|
|
.Sy type ,
|
|
.Sy mode ,
|
|
.Sy gname ,
|
|
or
|
|
.Sy gid ,
|
|
and
|
|
.Sy uname
|
|
or
|
|
.Sy uid ,
|
|
.Sy device
|
|
(in the case of block or character devices), and
|
|
.Sy link
|
|
(in the case of symbolic links).
|
|
If
|
|
.Sy time
|
|
isn't provided, the current time will be used.
|
|
If
|
|
.Sy flags
|
|
isn't provided, the current file flags will be used.
|
|
Missing regular file entries will be created as zero-length files.
|
|
.It Fl f Ar free-files
|
|
Ensure that a minimum of
|
|
.Ar free-files
|
|
free files (inodes) exist in the image.
|
|
An optional
|
|
.Ql %
|
|
suffix may be provided to indicate that
|
|
.Ar free-files
|
|
indicates a percentage of the calculated image size.
|
|
.It Fl M Ar minimum-size
|
|
Set the minimum size of the file system image to
|
|
.Ar minimum-size .
|
|
.It Fl m Ar maximum-size
|
|
Set the maximum size of the file system image to
|
|
.Ar maximum-size .
|
|
An error will be raised if the target file system needs to be larger
|
|
than this to accommodate the provided directory tree.
|
|
.It Fl N Ar dbdir
|
|
Use the user database text file
|
|
.Pa master.passwd
|
|
and group database text file
|
|
.Pa group
|
|
from
|
|
.Ar dbdir ,
|
|
rather than using the results from the system's
|
|
.Xr getpwnam 3
|
|
and
|
|
.Xr getgrnam 3
|
|
(and related) library calls.
|

|
Set the file system sector size to
|
|
.Ar sector-size .

|
|
Two or more numbers may be separated by an
|
|
.Dq x
|
|
to indicate a product.
|
|
Each number may have one of the following optional suffixes:
|
