[GTALUG] Enlarging /boot

[William Witteman]

Thanks to everyone who responded!

As Lennart points out, /boot can't be an LVM, and the whole rest of the
disk was an LVM partition.  Those get bigger easily, but not smaller.

It was easiest for me to copy my /home onto a backup drive and reinstall
Debian.  My experiment with LVM and "automatic" partitions was a failure -
my workflow is better suited to a / and a /home.

Thanks again!
