yes, that's correct. The sda1,sdd1 thing replaces the size argument as the size
is specified implictly by the size of the partitions. And the partitions are
created as before. Things should work the same way for LVM physical volume
groups.

Two comments in my proposal were not correct:

...
primary /boot     20-100        rw                  ext3
# create a primary partition /dev/hda1 with a size of 20 MB and mount it
# read-write as /boot; it is formatted using ext3 filesystem
...

Here not a size of 20 MB, but a size between 20 MB and 100 MB is specified.

...
logical /var      10%-      rw                  ext3
# make /dev/hda7 at least 2000 MB
...

The size of the partition is at least 10% of the overall disk size, and not
(necessarily) 2000 MB.

Regards,
Michael
