Of course.

ISTR I did,  but could be wrong, its quite a ways back up the log by now, so 
I'll plead oldtimers.  Since I retired at 67 and I've been collecting SS for 
8 years already, that isn't too much of a stretch. :)

Chuckle, that beats me, my first install was RH5.0.

I need to install F12 here at some point, and it sure would be a hell of a 
lot easier if F10 had enough libraries installed to run gparted to prepare a 
drive the way _I_ want it and tell anaconda to go pound sand.  For instance, 
why will it not accept a /boot partition specified for more than 199 
megabytes?

Why will it not accept a separate /root partition?

Why will it not accept a separate /var partition?

Or a separate /etc partition?

When I lost my boot drive about a month ago, I used gparted to set a drive up 
the way my experience said it should be, then rsync'd everything to the new 
partitions, fixed the new drives fstab to use the labels I put on with 
gparted, moved the drive to the sata0 connector figuring I could boot the F10 
dvd in the rescue mode and do a grub-install.  But my F10 dvd had faded, so I 
had to get a friend to dl and burn me a fresh copy, which I then used to 
install grub.  On the reboot I was back to a fully working F10, with one very 
noticeable difference, the machine is now 2-3x faster.  And has remained so.

All those separate partitions that the installer won't let you do?  I'll let 
a df report testify.
