If you install anaconda and run list-harddrives-stub manually, you'll see
what it's doing.
Basically, it returns something like this.
sda 1907729.08594
sdb 1907729.08594
sdc 1907729.08594
the set $(list-harddrives) bit of code, assigns these values to the $1 $2
$3 ... variables. So when you need to refer to the drives in the
partitioning snippet code, you can just refer to the first drive and $d1,
then second as $d2 etc.
Remember to escape the "$" in the snippet tho..
for example the snippet code would look like this....
set \$(list-harddrives)
let numd=\$#/2 # Number of harddrives
d1=\$1 # Device for first drive
d2=\$3 # Device for first drive
d3=\$5 # Device for first drive
etc...
Nice thing about this is it lets you make some decisions based on the
existence of the "d" variables. So if "$d3" exists on a certain
machine,
add it to the config, otherwise, don't include it's partitioning info etc.
Quite handy
Hope this helps

Can you explain that in more detail? I'm not quite sure I follow
what
it's supposed to do. Do I continue with $3 for the second drive and $4 for
the second drives size?
Thanks.
