ext3 in debian image

[sandro]

Hi.
I'm reading the guide to build a Debian fs on the Olinuxino at this address:
http://olimex.wordpress.com/2012/10/12/building-bootable-sd-card-with-debian-linux-image-for-a13-olinuxino/

It says to do a ext3 partition on the flash

mkfs.ext3 /dev/sdX2

but I know that can cause problems because ext3 is journaling fs. This feature causes the fs to be written to a large number of times, so that the flash will soon spoil.
It's not better a ext2?
