Which rpm package supplies isofs.ko kernel module?
Environment
- Red Hat Enterprise Linux 5
- Red Hat Enterprise Linux 6
- Red Hat Enterprise Linux 7
Issue
- Which rpm package supplies
iso9660support for CD/DVD media mounts. - Is isofs.ko module is available in the kernel package.
- With Fedora Core 20 the kernel package supplies the isofs.ko file. Is it available for RHEL 6 and RHEL 7.
Resolution
-
For RHEL 5 and RHEL 6:
- The
isofssupport is built into the kernel. There is no module load required in order to useisofs.
Eg:- - Run
modinfoto check whether it is loaded or not:
- The
# modinfo iso9660
modinfo: could not find module iso9660
- Check from the kernel configuration file:
# cat /boot/config-2.6.18-274.el5 | grep -i iso9660
CONFIG_ISO9660_FS=y
-
For RHEL 7:
- The iso9660 module is loaded into the kernel which can be unloaded if required.
Eg:- - Run
modinfoto check whether it is loaded or not:
- The iso9660 module is loaded into the kernel which can be unloaded if required.

Y = Module is compiled directly in kernel.
N = Module is not complied into the kernel.
