NAME
mk9660, pump - create and write ISO-9660 CD-ROM images
SYNOPSIS
disk/mk9660 [-c] [-e] [-a absfile] [-b bibfile] [-n notfile]
[-o ofile] ifile
disk/pump [-t target] [-m meg] [-n nproc] [ifile]
DESCRIPTION
Mk9660 reads the file system archive ifile as prepared by
mkfs(8) and produces a file system on ofile (cd-rom by
default) in ISO-9660 format.
The options to mk9660 are:
c Convert all file names in the file system so that they
conform to 9660 standards. (Roughly this is eight or
fewer single case alphanumerics followed by an optional
period and three or fewer single case alphanumerics.)
File names that conform are converted from lower case
letters in the input filesystem to upper case in the
output file system. Files that do not conform are
renamed to Fnumber and directories are renamed Dnumber.
A file named _CONFORM.MAP is created in the root of the
output file system with old-name new-name pairs of all
converted files.
e Add a system-use field to every directory record that
contains the name, uid, gid and mode of the file. With
or without this extension, directory records conform to
the 9660 standard and should be able to be read on
other systems.
a Places the named file to the abstract field of the pri-
mary volume descriptor. The file must be in the root
directory.
b Places the named file in the bibliographic field of the
primary volume descriptor. The file must be in the
root directory.
n Places the named file in the copyright field of the
primary volume descriptor. The file must be in the
root directory.
All dates in the output file system are set to the date the
command was executed. The volume identifier field of the
primary volume descriptor is set to the last component of
ifile. The system identifier field of the primary volume

descriptor is set to PLAN 9, and should be keyed to the
interpretation of the system-use fields of the directory
records.
Pump reads ifile (cd-rom by default) and issues the SCSI
commands to write a Phillips CDD 521 Compact Disk Recorder.
The file is uninterpreted, but it can be a 9660 file system
as produced by mk9660(8). The CD writer requires a sustained
data rate of 305,600 bytes/sec. To get this rate on an Eth-
ernet from a file server, pump creates several processes
that read ahead into shared buffers. Even so, the file sys-
tem should have fast disks or multiple disks with inter-
leaved overlapping seeks. The options to pump are:
t specifies the SCSI target (default 1) for the CD
writer.
m specifies the total buffer space (default 10) in mega-
bytes.
n specifies the number (default 3) of read-ahead pro-
cesses.
BUGS
The pump command does not correctly set up the SCSI bus.
Use the scuzz(8) command to open the desired SCSI target.
