Oops, I read that wrong the first time. You do not want a comma between iso9660 and user. My brain read them all as the option section and the lack of a comma would have been wrong in that case.

Interesting.  Putting the comma in all 6 lines made them all fail one at
a time.  The failure message in /var/log/boot.log says

mount: unknown filesystem type 'loop'
mountall: mount /tftpboot/howtogeek/linux/ubu1004DL32 [745] terminated
with status 32

and I find no reference to loop in a man fstab though I do in mount.  I
am wondering if the guide I am using may have been written by someone
who manually mounted as a loop device and then wrote the article and
assumed it was a valid type for fstab. <mumbling as I speculate>  I have
never understood loop devices.  Is that why you said you did not know
why any of them worked?

    As for the nfs stuff, nfs requires you to add either the
    "subtree_check" or "no_subtree_check" option to the exports file for
    every line these days.

        Problem is that only the middle two seem to work.  The first one (or
        more) show an error on screen and give 2 options before the gdm
        login
        but gdm comes up too soon to do anything.  After logging in I find

        from processing /etc/exports for nfs.  I don't think this means
        anythoing about why only 2 of the 6 gets mounted.  Any ideas?
