But this is a valid point, thank you.

For the present I think Linux's binary packaging system (apt or yum) is still more advanced than ours. However, the separation of the "base system" and "packages" as seen in FreeBSD seems to me a great, unique advantage. Another point in FreeBSD's favour. > - src.conf, make.conf and easy world rebuild ; Very few need this nowadays at the time of cattle servers (as opposed to pet servers). > - LLVM instead of GCC. If it gives measurable advantages in productivity, performance or security, I'd be happy to learn more about that.

If this is really so, why is FreeBSD planning to migrate to Linux's ZFS implementation? --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --oJ71EGRlYNjSvfq7 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJeR3w/AAoJEA2k8lmbXsY0QCUH/1TU4y/rt28ViAHWgHGmnNu6 A5As5iqeUqq+v9TYjXjef/IydqF8vN5L6fP2xmelrKL1XckJG+l2BxSwUWe6u8dL hIaIjdklfIvi1nJu60E3RFk4ksyL6mUlHoayuirQYXpYJskoqpTjgisO29ITqjrX Ity40QdxZC8RWoigpoENraG3g1uSZ7Zs6WDZRkShaLR+68aKOLjV6r6dRGCsDcYh yE0mQUqpjHpbwUsmZFWK2Dn8PmG8tqGetYT2/ceeiIXKbDsGwAgcqXud4wrLvN/f 7bWAzhMDO4NdvO/NHtidJBpQXlTWiMYFPBzkxf+jw4oq70ydJyKrzlghgdGRXoM= =tyt3 -----END PGP SIGNATURE----- --oJ71EGRlYNjSvfq7--
