Cause:

Some Linux systems have enhanced security that mount CDROM/DVD devices with the "noexec" option.   This prevents applications/scripts from being executed directly from the device when mounted.

Resolution:

To resolve this issue, turn off the "noexec" option after the CD/DVD is mounted.  This can be done using the mount command with the "remount" option combined with the "exec" option.  This will then allow the installer to run directly from the CD/DVD.

Here is an example ot the command.

First, here is a device mounted with the noexec option:

zephyr:~ # mount | grep DISC2
/dev/hdb on /media/DISC2 type subfs (ro,noexec,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)
zephyr:~ # 

Here is an attempt to run the installer:

zephyr:~ # cd /media/DISC2/galaxy/
zephyr:/media/DISC2/galaxy # ./cvpkgadd
-bash: ./cvpkgadd: /bin/sh: bad interpreter: Permission denied
zephyr:/media/DISC2/galaxy #

Here is the command to remove the "noexec" option on the mounted CD/DVD:

zephyr:/media/DISC2/galaxy # mount -o remount,exec /media/DISC2
zephyr:/media/DISC2/galaxy # mount | grep DISC2
/dev/hdb on /media/DISC2 type subfs (ro,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)
zephyr:/media/DISC2/galaxy #

The "noexec" option is no longer there, and the installer will now run.
