From Nathan Whitehorn (nwhitehorn at freebsd dot org):
Add code to generate bootable ISOs on Powermac and CHRP systems.
Synthesize some partition maps (APM and MBR, respectively) pointing
to (a) the whole disk, and (b) relevant El Torito boot images that
have been added by other code. These partition maps are a little
bit funny looking, but they seem to work. FreeBSD has been using
this successfully in their release generation on powerpc, as well
as generating all non-SPARC install media. SPARC support could
probably be added as an extension of this patch.

PR/45285: Martin Matuska: makefs does not properly convert ISO level 1 and 2
filenames (buffer overflow)
makefs does not properly verify the maximum filename length in the
special "." case for both ISO level 1 and ISO level 2 filename
conversion. This creates broken images or causes a buffer overflow
(ISO level 2).
ISO level 1:
If a filename contains only dots or up to 8 characters followed by
dots the 8+3 limit check doesn't work.
ISO level 2:
If a filename contains a dot in the first 30 characters and a dot
on the 30th character, the length limit check doesn't work and the
buffer is overflowed.
$ mkdir level1
$ touch level1/12345............

|
.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 .
|
|
If any optional directory trees are passed in the
|
|
.Ar extra-directory
|
|
arguments, then the directory tree of each argument will be merged
|
|
into the
|
|
.Ar directory
|
|
or
|
|
.Ar manifest
|
|
first before creating
|
|
.Ar image-file .
|
|
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 endian
|
|
Set the byte order of the image to
|
|
.Ar endian .
|
|
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
|
|
Treat duplicate paths in an mtree manifest as warnings not error.
|
|
.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 mtree-specfile
|
|
Use
|
|
.Ar mtree-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 ,
|
|
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 userdb-dir
|
|
Use the user database text file
|
|
.Pa master.passwd
|
|
and group database text file
|
|
.Pa group
|
|
from
|
|
.Ar userdb-dir ,
|
|
rather than using the results from the system's
|
|
.Xr getpwnam 3
|
|
and
|
|
.Xr getgrnam 3
|
|
(and related) library calls.
|
|
.It Fl o Ar fs-options
|
|
Set file system specific options.
|
|

|
|
is a comma separated list of options.
|
|
Valid file system specific options are detailed below.
|
|
.It Fl p

|
|
.Fl Z
|
|
flag.
|
|
.It Fl R Ar roundup-size
|
|
Round the image up to
|
|
.Ar roundup-size .
|
|
.Ar roundup-size
|
|
should be a multiple of the file system block size.

This option only applies to the
|
|
.Sy ffs
|
|
file system type.
|
|
.It Fl S Ar sector-size
|
|

|
|

|
.Pa pathname ,
|
|
where the timestamps are derived from that file, or an integer
|
|
value interpreted as the number of seconds from the Epoch.
|
|
Note that timestamps specified in an
|
|
.Xr mtree 5
|
|
spec file, override the default timestamp.
|
|
.It Fl t Ar fs-type
|
|
Create an
|
|
.Ar fs-type
|

file system image.
|
|
The following file system types are supported:
