I was actually thinking if I just enlarge it, delete and add it back 
larger, that the file system and files would still be there.  I'd just 
need to 'grow' the file system to see the whole thing.  Either way, if I 
lose data on build-part, no biggie.  My basic process is this.  I run 
eix-sync && emerge -auDN world on my OS.  Once I get everything ready to 
build, I mount and use rsync to copy the main OS over.  It just updates 
so it doesn't take long plus it's on a m.2 stick.  Then I chroot in, run 
emerge -uDN world and then when done, copy the binaries over and add the 
-k option to emerge for the main OS.  So if I lose everything on 
build-part, my little script will just copy it back over again.

Since my update is done, time to logout and back in.  Fair size KDE 
update this weekend.  I'll work on resizing things in a bit.  It's nice 
outside so I'm a busy bee.

Thanks to all.
