Agreed. Even better is to avoid it. Small ext{3,4} file systems
shrink acceptably well. But larger ext{3,4} file systems can take a
very long time to shrink. I once made the mistake of trying to shrink
a 600G filesystem. The operation was eventually successful. But it
took 10 days to complete! And once I started it there was no other
option than to let it complete.
