.Sh NAME
|
|
.Nm mount_isofs
|
|
.Nd mount an ISO-9660 filesystem
|
|
.Sh SYNOPSIS
|
|
.Nm mount_isofs
|
|
.Op Fl F Ar fsoptions
|
|
.Op Fl norrip
|
|
.Op Fl gen
|
|
.Op Fl extattr
|
|
.Pa special

.Pa node
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm mount_isofs
|
|
command attaches the ISO-9660 filesystem residing on
|
|
the device
|
|
.Pa special
|
|
to the global filesystem namespace at the location
|
|
indicated by
|
|
.Pa node .
|
|
This command is normally executed by
|
|
.Xr mount 8
|
|
at boot time.
|
|
.Pp
|
|
If the filesystem includes Rockridge extensions, they are
|
|
used unless the
|
|
.Fl norrip
|
|
flag is used. If that option is given to
|
|
.Nm
|
|
then the Rockridge extensions will be ignored.
|
|
.Pp
|
|
Version numbers on files are normally stripped on directory listings.
|
|
If you want to see those, use the
|
|
.Fl gen
|
|
flag.
|
|
Otherwise, if there are files with different version numbers on the disk,
|
|
only the last one will be listed.
|
|
In either case, you may open a file with or without explicitly stating the
|
|
version number.
|
|
.Pp
|
|
If a disk contains extended attributes, they are normally ignored.
|
|
You can enable the usage of extended attributes with the
|
|
.Fl extattr
|
|
flag.

.Sh BUGS
|
|
The isofs filesystem should support the original "High Sierra"
|
|
("CDROM001") format;
|
|
it does not.
|
|
.Pp
|
|
POSIX device node mapping is currently not supported.
|
|
.Pp
|
|
Version numbers are not stripped if Rockridge extensions are in use.
|
|
In this case, accessing files that don't have Rockridge names without
|
|
version numbers gets the one with the lowest version number and not
|
|
the one with the highest.
|
|
.Pp
|
|
The filesystem name might need some rethinking, and some would
|
|
say it should run as a user process.
|
|
.Pp
|
|
There is no ECMA support.
|
|
.Sh HISTORY
|
|
The
|
|
.Nm mount_isofs
|
|
utility first appeared in NetBSD 0.8.
|
|
Handling of Rockridge extensions was added for NetBSD 0.9.
