mkboottape(1M)mkboottape(1M)NAMEmkboottape - make a boot tape filesystem
SYNOPSIS
/etc/mkboottape [-f output_file] [-l | -x [file ...] | file ...]
DESCRIPTIONmkboottape is used to build, list, or extract "boot tape filesystems".
Booting from tape is no longer supported. However, the tape filesystem
format is still used in the sa file used in booting from CDROM.
A tape filesystem consists of a special directory that contains the list
of filenames, sizes, and offsets, and from one to 20 files. Filenames
can be up to 16 characters in length.
The following options are understood:
-l List the contents of the boot tape. In this case the
file arguments are ignored.
-f [output_file] Specify an alternate output file or device. The
default is /dev/tape.
-x [file ...] Extract files from the boot tape. If no filenames are
given, all files are extracted. Extracted files have
their original size (they are not null padded to a
block multiple).
The typical use for this program is to create an output file that is used
in booting from CDROM, or to extract files from that "filesystem". The
PROM monitor understands the boot tape format.
NOTES
Unless you have means to create a standalone program, this utility is
useful only listing or extracting the files, or creating new boot images
from previously extracted files. In some cases it can be used to extract
the standalone programs into a directory, because most standalone
programs can be booted from the filesystem using sash or over a network.
