[SLUG] Can't execute program from CDROM

[Ken Caldwell <kencaldwell@xxxxxxxxxxxxxxxx>]

Hi,
I ran into the following problem when trying to install StarOffice from
a CD which comes with the latest pc world minibook.

The directions say to login as root, mount the CD and while in X execute
the program. If I do this I get

adler:~# /cdrom/office/staroffice/so-5_2-ga-bin-linux-en.bin /net
bash: /cdrom/office/staroffice/so-5_2-ga-bin-linux-en.bin: Permission denied

Read and execute permissions are set on the file and all the directories
in the chain.  The options in /etc/fstab were: defaults,ro,user,noauto
but to be sure I tried again after changing them to:
ro,suid,dev,exec,noauto,user,async but the result was the same. If I
just copy the file to /tmp I can then execute it.  Why is it so?

regards,

Ken
