Oh, and change fstab. It's not that simple if /usr is on LVM, / is not large enough to hold /usr and resizing the partition is really tricky. In that case, the simplest option is to start using an initramfs. Once that is working, you can get rid of the separate root partition and move that filesystem into the VG too. --=20 Neil Bothwick WinErr 004: Erroneous error - Nothing is wrong --Sig_/qe6BQx+L_ebVrzdpMs=ojx5 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (GNU/Linux) iEYEARECAAYFAlJHMxoACgkQum4al0N1GQN0ZQCgygycKTz6wKjNxHJcaYnNgwbM 6WwAmwU3zQRoXX3D3+bkY+37nrcyKpR0 =xjYn -----END PGP SIGNATURE----- --Sig_/qe6BQx+L_ebVrzdpMs=ojx5--
