particionamento de discos

boa tarde.
estou com uma duvida.
após executar um particionamento manual em um debian 7.0.6 obtenho o seguinte cenário.

conteudo do comando df -h :

Sist. Arq. Tam Usad Dispon. Uso% Montado em
rootfs 303G 786M 287G 1% /
udev 10M 0 10M 0% /dev
tmpfs 390M 284K 389M 1% /run
/dev/disk/by-uuid/4938f268-1f35-4dc4-b713-77781505fcdc 303G 786M 287G 1% /
tmpfs 5,0M 0 5,0M 0% /run/lock
tmpfs 4,5G 0 4,5G 0% /run/shm
/dev/sdc1 1,8T 196M 1,7T 1% /bkp
/dev/sda2 4,6G 155M 4,2G 4% /boot
/dev/sdb1 1,8T 196M 1,7T 1% /home
/dev/sda5 133G 327M 126G 1% /var

observem que o meu / se encontra com o sistema de arquivos como rootfs e mais abaixo onde deveria estar o /dev/sda1 ele monta no dispositivo
/dev/disk/by-uuid/4938f268-1f35-4dc4-b713-77781505fcdc.

importante resaltar que este particionamento foi montado manualmente na instalação pois o /home esta montado em outro disco com controle para implantação de cotas de usuários.

executei um teste montando o particionamento de forma automatica e este montou sem problema algum.

entendo que o correto seria a partição estar igual as demais como sistema de arquivos journaling ext4.

alguém poderia me apontar onde estou errando no processo ?

abaixo segue resultado do comando mount e conteudo do fstab.
