[NBLUG/talk] RAID1 and partitions

[Omar Eljumaily]

I wouldn't make swap its own RAID partition.  The reason is why bother?  
/boot used to need to be ext2 for old versions of Grub.  I think that's 
why it would take up all of md0.  I've read that putting /boot inside 
LVM is unstable, or at least it used to be. Maybe it will work nowadays 
to put /boot, swap, and / all inside LVM volume using a single md0.
