Re: [vox-tech] mount difficulties


one of the most important questions when something like this arises is:

     what has changed since it last worked?

did you recompile the kernel?  update any packages?

next, look in /var/log/messages for anything involving insmod/modprobe not
finding anything.  do:

	locate iso9660

see if any object files come up in /lib/modules or /usr/src/linux.  if so, do
an insmod -f <path>/iso9660.o

also, look in /proc/filesystems to make sure your kernel can register iso9660

the OS consults fstab on the fly, so your changes are immediate.
