Help with fstab additions

[Dazed_75]

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?
