ISO grub menu kernel options for "Troubleshooting" menu

[firkin-gadabout]

When trying to install from ISO I was forced to use the basic graphics option in the troubleshooting menu. I discovered that the kernel options appended in the isolinux.cfg specify the wrong disk label.

See here the correct append parameter. Specifically the \x203\x20 in the label

label linux
  menu label ^Install Rockstor
  menu default
  kernel vmlinuz
  append initrd=initrd.img inst.stage2=hd:LABEL=Rockstor\x203\x20x86_64 quiet ip=dhcp ks=hd:LABEL=Rockstor\x203\x20x86_64:/ks.cfg

Then in grub troubleshooting menu both the vesa plus the rescue install have \x203.0\x20 and the correct label is simply 3 not 3.0

label vesa
  menu indent count 5
  menu label Install Rockstor 3.0 in ^basic graphics mode
  text help
	Try this option out if you're having trouble installing
	Rockstor 3.0.
  endtext
  kernel vmlinuz
  append initrd=initrd.img inst.stage2=hd:LABEL=Rockstor\x203.0\x20x86_64 xdriver=vesa nomodeset quiet
