Posso montar uma partição ext4 na partição “/”?

Question

Ontem, criei uma partição ext4 a partir da partição do windows. E agora, quero montá-lo automaticamente na inicialização. Mas estou tendo alguns problemas:

Possoescolher"/" para montar o ponto? Aqui está o meu /etc/fstab :

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda3 during installation
