start point on end point of boot partition

[dt47]

Hi,

although I haven't encountered any problems so far, I don't understand, why the end point of sda1 is the start point of sda2.

fdisk -l /dev/sda

Disk /dev/sda: 146.2 GB, 146163105792 bytes
255 heads, 63 sectors/track, 17769 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00052aa9


   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          66      523264   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              66       17770   142213120   8e  Linux LVM

Is this on purpose? It was automatically set up like this with the pve cds v2.2.
