CentOS - May 2016 - Verifing: CentOS 5 cannot resize a *live* root filesystem

Just want to verify: CentOS 5's FS utilities are too old to safely resize a 
*live* (mounted, etc.) root file system (and the CentOS 5 installer/rescue 
system does not include either resize2fs or fsadm utilities).

I am presuming I will need a full-fledged Live CD/DVD to resize the root file 
system.

This is for an old 32-bit laptop that presently has CentOS 5.11 on it -- I 
want to shrink the root file system (it is LVM) and make a separate /home file 
system, then upgrade it to something newer (not C6, since it is not PAE --
I'm
*hoping* Ubuntu's 32-bit installer can deal with a non-PAE 32-bit system).

I don't know of _any_ filesystem that supports live shrinking. Live 
expansion, yes. Live shrinking, no. The C5 install/rescue CD and DVD do
include resize2fs.

Ubuntu is _not_ one of the few distributions that still support non-PAE 
32-bit. From what I can find, Lubuntu and Xubuntu 12.04 were the last 
versions to support non-PAE. Sorry.

                 Do NOT delete it.

Btrfs supports live shrinking of filesystem.
