62.Op Ar extra-directory ...
63.Sh DESCRIPTION
64The utility
65.Nm
66creates a file system image into
67.Ar image-file
68from the directory tree
69.Ar directory
70or from the mtree manifest
71.Ar manifest .
72If any optional directory trees are passed in the
73.Ar extra-directory
74arguments, then the directory tree of each argument will be merged
75into the
76.Ar directory
77or
78.Ar manifest
79first before creating
80.Ar image-file .
81No special devices or privileges are required to perform this task.
82.Pp
83The options are as follows:
84.Bl -tag -width flag
85.It Fl B Ar endian
86Set the byte order of the image to
87.Ar endian .
88Valid byte orders are
89.Ql 4321 ,
90.Ql big ,
91or
92.Ql be
93for big endian, and
94.Ql 1234 ,
95.Ql little ,
96or
97.Ql le
98for little endian.
99Some file systems may have a fixed byte order; in those cases this
100argument will be ignored.
101.It Fl b Ar free-blocks
102Ensure that a minimum of
103.Ar free-blocks
104free blocks exist in the image.
105An optional
106.Ql %
107suffix may be provided to indicate that
108.Ar free-blocks
109indicates a percentage of the calculated image size.
110.It Fl D
111Treat duplicate paths in an mtree manifest as warnings not error.
112.It Fl d Ar debug-mask
113Enable various levels of debugging, depending upon which bits are
114set in
115.Ar debug-mask .
116XXX: document these
117.It Fl F Ar mtree-specfile
118Use
119.Ar mtree-specfile
120as an
121.Xr mtree 8
122.Sq specfile
123specification.
124This option has no effect when the image is created from a mtree manifest
125rather than a directory.
126.Pp
127If a specfile entry exists in the underlying file system, its
128permissions and modification time will be used unless specifically
129overridden by the specfile.
130An error will be raised if the type of entry in the specfile
131conflicts with that of an existing entry.
132.Pp
133In the opposite case (where a specfile entry does not have an entry
134in the underlying file system) the following occurs:
135If the specfile entry is marked
136.Sy optional ,
137the specfile entry is ignored.
138Otherwise, the entry will be created in the image, and it is
139necessary to specify at least the following parameters in the
140specfile:
141.Sy type ,
142.Sy mode ,
143.Sy gname ,
144or
145.Sy gid ,
146and
147.Sy uname
148or
149.Sy uid ,
150and
151.Sy link
152(in the case of symbolic links).
153If
154.Sy time
155isn't provided, the current time will be used.
156If
157.Sy flags
158isn't provided, the current file flags will be used.
159Missing regular file entries will be created as zero-length files.
160.It Fl f Ar free-files
161Ensure that a minimum of
162.Ar free-files
163free files (inodes) exist in the image.
164An optional
165.Ql %
166suffix may be provided to indicate that
167.Ar free-files
168indicates a percentage of the calculated image size.
169.It Fl M Ar minimum-size
170Set the minimum size of the file system image to
171.Ar minimum-size .
172.It Fl m Ar maximum-size
173Set the maximum size of the file system image to
174.Ar maximum-size .
175An error will be raised if the target file system needs to be larger
176than this to accommodate the provided directory tree.
177.It Fl N Ar userdb-dir
178Use the user database text file
179.Pa master.passwd
180and group database text file
181.Pa group
182from
183.Ar userdb-dir ,
184rather than using the results from the system's
185.Xr getpwnam 3
186and
187.Xr getgrnam 3
188(and related) library calls.
189.It Fl o Ar fs-options
190Set file system specific options.
191.Ar fs-options
192is a comma separated list of options.
193Valid file system specific options are detailed below.
194.It Fl p
195Deprecated.
196See the
197.Fl Z
198flag.
199.It Fl R Ar roundup-size
200Round the image up to
201.Ar roundup-size .
202.Ar roundup-size
203should be a multiple of the file system block size.
204This option only applies to the
205.Sy ffs
206file system type.
207.It Fl S Ar sector-size
208Set the file system sector size to
209.Ar sector-size .
210.\" XXX: next line also true for cd9660?
211Defaults to 512.
212.It Fl s Ar image-size
213Set the size of the file system image to
214.Ar image-size .
215.It Fl t Ar fs-type
216Create an
217.Ar fs-type
218file system image.

225.El
226.It Fl x
227Exclude file system nodes not explicitly listed in the specfile.
228.It Fl Z
229Create a sparse file for
230.Sy ffs .
231This is useful for virtual machine images.
232.El
233.Pp
234Where sizes are specified, a decimal number of bytes is expected.
235Two or more numbers may be separated by an
236.Dq x
237to indicate a product.
238Each number may have one of the following optional suffixes:
239.Bl -tag -width 3n -offset indent -compact
240.It b
241Block; multiply by 512
242.It k
243Kibi; multiply by 1024 (1 KiB)
244.It m
