How does that spare the SSD when frequently written directories, like /var and /usr/portage on partially on the SSD? If you want to keep them off the SSD, you must not use LVM like this. Forget LVM, forget a separate /boot, just stick / on the SSD and mount the likes of /var on the SD card. I use LVM on my Eee, but that's because it has two SSDs, I wouldn't dream of including the SD card in there. --=20 Neil Bothwick C&W music backward: get yer dog, wife, job, truck, kids, and sobriety back. --Sig_/_mWARxJEFMMWBCr63fkUla9 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (GNU/Linux) iEYEARECAAYFAkpABMIACgkQum4al0N1GQNQCwCcCSuLbNvvbhZ4lgVAg43xBTzZ LUUAn2kyN+8oMxKtkJvWup8EY+dPXbBx =S/S7 -----END PGP SIGNATURE----- --Sig_/_mWARxJEFMMWBCr63fkUla9--
