[CVALE] Well, I think I've tried everything...

Hi Michael,

Don't forget that there can be only 4 primary partitions.  If you want to have more you have to make 
one of the primary partitions "extended" then add a bunch more "logical" partitions in the 
"extended" partition.  As far as I know you can't use the primary partition that you've made 
"extended" directly, can only use the logical partitions under it.

Don't forget to make a file system in each of the partitions.  It should happen as part of the 
installation.

I don't know about the 16 partition limit.  I've used 10 or 12 partitions without a problem.  I just 
use fdisk and it works fine for me.  I only have occasionally problems with resizing involving DOS 
partitions, but that's a long time known problem with workarounds.

You could put /boot closer to the beginning of the disk (lower cylinder number) but I don't know if 
that matters these days like it did in the past.  I usually put system stuff (root, boot, swap) near 
the beginning and data/application paritions afterwards.  I makes it easier to create and delete 
data partitons.  But of course the opposite would be true if one's data remained static but new 
operating systems were being deleted and added.  :-)

You appear to have a ROOT partition (/) as well as a partition called "root" mounted on ROOT (/). 
It's okay so long as know where you're mounting stuff.

Although it's Linux, don't forget to try rebooting when you make disk partition changes.

Basic stuff but it doesn't hurt to check.  I trip over simple stuff all of the time.
