Actually, on the normal RELENG_7/i386 install (i.e. done by buildworld/installworld), I get Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 257998 50422 186938 21% / /dev/ad0s1e 4129310 143676 3655290 4% /usr Note that you must supply INSTALL_NODEBUG=3Dyes for installkernel, and the numbers shown are for WITHOUT_PROFILE=3Dyes. Amd64 takes ~230Mb for merged / and /usr, this is both due to increased binary sizes and lib32. --ensexbfp9Ul6anXl Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEARECAAYFAkiUADQACgkQC3+MBN1Mb4iy3gCfYFpptXtjvAWKmcUW2FUsGkSw wrMAn0xCENPbGyjnr9cUpERlbD2oCstR =JIjY -----END PGP SIGNATURE----- --ensexbfp9Ul6anXl--
