However, I see no argument for why that should be the case. Thinking about it, I suppose this would make sense in an enterprise setting where everything is diskless. If you PXE boot, put rootfs on iSCSI and have /usr on a NFS mount, this would work very well. Claiming that people show a lack of understanding when you never explain this, however, is definitely the wrong thing to do. With that said, I have a few questions: 1. Why does no one mention the enterprise use case at all? 2. Why not make rootfs a NFS mount with a unionfs at the SAN/NAS device? 3. Why not let the users choose where these directories go and support both locations? --------------enig31650DA780981A4CBBED2E65 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJPYR4NAAoJELFAT5FmjZuEvjAQAMO+iRSp6qvic8RDODzoH+ON s8AWo/iKkpsZEKzpXY52iHUiayLNqjc0rs0XWStNftG9maHauhjZVYxlRlFeCph6 nwCyy1Jk+uWkp0PA590uVhcKYrRUdJbjksRmgI3bDy3p2/WvUC81TNhI29PSqJlS k/t0IorvB85GWcNIgOlHcXeBstdY0NJfSxQZHm23hkDQqkyYhbdmvd5GTCl1QaBG /LWfYI7nC+KXhe9dxydJWF398KQhSkKIkNE7oeeXRP4z3bYj9nQkkfE6Mxf0F/Zy M5FlGz9aaMEjmGEdbKXouXG3t3Wgs+N7Fb4U1n9u2JPf7G/ENU93tFV3pak94mPd LUtG1FM7CEd94oADC56WYrkVP2s0o3HwDxKwgH11yZgkTHNzSY+Q0UX06DC+OJif lsudxBGSo/g3zWzJxcMc1LHBTv+u+wguV+gz90tOis11LjXqhA6jAGDJB79Vy2/1 WsfTigfHiK5pck3KLwEgV4euD8DEa9wpFyTGFMPAoaKxtN7ILKHNLHOtxaO43rQM uIFc39YvvRDkODOYea8QwcAlKBMkDs8EZjXNGzZKDokQeVJuAcmUDn3o71t4Yw+4 AHxvJKnrssqHRVF46O5Jpeto06RhAfzp3+IrulbT/ZyfL4VJp2GwyANg/+c7oELP r9PXCC+emf/PateOu4I+ =n0le -----END PGP SIGNATURE----- --------------enig31650DA780981A4CBBED2E65--
