[lfs-support] /etc/fstab

I'd appreciate it if somebody could please have a look at my /etc/fstab 
file shown below and let me know if it's OK. I've searched this mailing 
list's archives and an example /etc/fstab I found was a bit different to 
mine. I also had a look at the /etc/fstab files on  a Ubuntu and Debian 
systems, but they weren't as detailed as mine.

In particular, I'd like to know whether it is my /boot partition or / 
partition that has to be checked by fsck. Is it OK for /boot to be ext3, 
or should I have made it ext2? Googling it suggests that it's probably 
better for it to be ext2, but ext3 should do fine as well.
