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. .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. .It Fl o Ar fs-options Set file system specific options. .Ar fs-options is a comma separated list of options. Valid file system specific options are detailed below. .It Fl S Ar sector-size Set the file system sector size to .Ar sector-size . .\" XXX: next line also true for cd9660? Defaults to 512. .It Fl s Ar image-size Set the size of the file system image to .Ar image-size . .It Fl t Ar fs-type Create an .Ar fs-type file system image. The following file system types are supported: .Bl -tag -width cd9660 -offset indent .It Sy ffs BSD fast file system (default). .It Sy cd9660 ISO 9660 file system. .El .It Fl x Exclude file system nodes not explicitly listed in the specfile. .El .Pp Where sizes are specified, a decimal number of bytes is expected. 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: .Bl -tag -width 3n -offset indent -compact .It b Block; multiply by 512 .It k Kibi; multiply by 1024 (1 KiB) .It m Mebi; multiply by 1048576 (1 MiB) .It g Gibi; multiply by 1073741824 (1 GiB) .It t Tebi; multiply by 1099511627776 (1 TiB) .It w Word; multiply by the number of bytes in an integer .El .\" .\" .Ss FFS-specific options .Sy ffs images have ffs-specific optional parameters that may be provided. Each of the options consists of a keyword, an equal sign .Pq Ql = , and a value. The following keywords are supported: .Pp .Bl -tag -width optimization -offset indent -compact .It Sy avgfilesize Expected average file size. .It Sy avgfpdir Expected number of files per directory. .It Sy bsize Block size. .It Sy density Bytes per inode. .It Sy fsize Fragment size. .It Sy maxbpg Maximum blocks per file in a cylinder group. .It Sy minfree Minimum % free. .It Sy optimization Optimization preference; one of .Ql space or .Ql time . .It Sy extent Maximum extent size. .It Sy maxbpcg Maximum total number of blocks in a cylinder group. .It Sy version UFS version. 1 for FFS (default), 2 for UFS2. .El .Ss CD9660-specific options .Sy cd9660 images have ISO9660-specific optional parameters that may be provided. The arguments consist of a keyword and, optionally, an equal sign .Pq Ql = , and a value. The following keywords are supported: .Pp .Bl -tag -width omit-trailing-period -offset indent -compact .It Sy allow-deep-trees Allow the directory structure to exceed the maximum specified in the spec. .\" .It Sy allow-illegal-chars .\" Unknown .\" .It Sy allow-lowercase .\" Unknown .It Sy allow-max-name Allow 37 instead of 33 characters for filenames by omitting the version id. .It Sy allow-multidot Allow multiple dots in a filename. .It Sy applicationid Application ID of the image. .It Sy archimedes Use the .Ql ARCHIMEDES extension to encode .Tn RISC OS metadata. +.It Sy chrp-boot +Write an MBR partition table to the image to allow older CHRP hardware to +boot. .It Sy boot-load-segment Set load segment for the boot image. .It Sy bootimage Filename of a boot image in the format .Dq sysid;filename , where .Dq sysid is one of .Ql i386 , .Ql mac68k , .Ql macppc , or .Ql powerpc . .It Sy generic-bootimage Load a generic boot image into the first 32K of the cd9660 image. .It Sy hard-disk-boot Boot image is a hard disk image. .It Sy keep-bad-images Don't throw away images whose write was aborted due to an error. For debugging purposes. .It Sy label Label name of the image. .It Sy no-boot Boot image is not bootable. .It Sy no-emul-boot Boot image is a .Dq no emulation ElTorito image. .It Sy no-trailing-padding Do not pad the image (apparently Linux needs the padding). .\" .It Sy omit-trailing-period .\" Unknown .It Sy preparer Preparer ID of the image. .It Sy publisher Publisher ID of the image. .It Sy rockridge Use RockRidge extensions (for longer filenames, etc.). .It Sy volumeid Volume set identifier of the image. .El .Sh SEE ALSO .Xr mtree 8 , .Xr newfs 8 .Sh HISTORY The .Nm utility appeared in .Nx 1.6 . .Sh AUTHORS .An Luke Mewburn .Aq lukem@NetBSD.org (original program) .An Daniel Watt , .An Walter Deignan , .An Ryan Gabrys , .An Alan Perez-Rathke , .An Ram Vedam (cd9660 support)
