Do you allocate all disk space to logical volumes during installation?

Yup. As I said in my article "Upgrading Linux" in the July '07 SysAdmin (now
ceased publication, dammit), I recommend LVM for /usr, /home, and *very* much
for /opt (since so much software these days wants to be there). I would *never*
use LVM for /boot or /

Size: 100M or so for /boot; 4G-8G for /, 20G for /usr, 4G for /var, ditto for
/tmp, and lots and lots for /opt and /home.
