The new partedUtil command must be used instead. The step to show the partition table with this new command are:

• First identify under /dev/disks the name of the system disk (it will be easy because usually is the only disk with more partitions:

• Then use the get or the getptbl options to see the partition size (but note that the partition size was already visible also in the first screenshot):

In this example you can see there are 7 partitions:·ÖÇøÆðʼÖÕÖ¹ÉÈÇø¼°³ß´ç¼ûͼ2

As you can see, a minimal installation can be feet also in small flash memory with only 1 GB. A curios thing the that some partitions are reported as linuxNative but they contain a FAT filesystem (are reported also by the df utility).

As written in the Richard¡¯s, the footprint of ESXi si increased to around 124MB in the 5.0 version, compare to the 70MB of 4.1 and the original 32MB or 3.5 version.
