I had a 128GB SSD, so I split it up more or less like so: 3GB to /boot (I run lots of test kernels) 20GB to / (more than enough in almost all cases) 90+GB to /home/dledford/repos The hard drives were 500GB, so once I took out the 128 or so GB that was mirrored to the SSD, that left another 375GB or so for the /home partitio= n. --=20 Doug Ledford GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband --------------enig5076EEFAEB8C3AAE4A3C0BDF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk4yt90ACgkQQ9aEs6Ims9gChwCfZ+pvWhUsuYcJNnLSgKPZsn0F WX0AoMMmzedfQv0zXKrGSLJvM/cetHK5 =wL7S -----END PGP SIGNATURE----- --------------enig5076EEFAEB8C3AAE4A3C0BDF--
