As long as you never recompile anything again, yes :) But as soon as you upgrade (say) libX11 to 64-bit, all dependant libraries and program will need to be brought up to 64-bit as well. You might as well do them all. I just did this 32->64 upgrade a few weeks ago, and since I had a ZFS root, I was able to do this: Snapshot+clone a new copy of my root filesystem (called root.amd64) Do a cross-build+installworld into that partition Install a 64-bit kernel into my /boot partition (installed as /boot/kernel.amd64 temporarily) Edit /boot/loader.conf and add vfs.root.mountfrom="zfs:local_pool/root.amd64" kernel="kernel.amd64" Edit /etc/fstab on root.amd64 to mount / from local_pool/root.amd64 Cross fingers, and reboot into amd64-land Portupgrade -fa (this step wan't flawless since I was also upgrading through the perl58 and gnome-2.24 updates, but still took less than 24 hours) All the while having my i386 kernel and root available to reboot back into if I screwed something up horribly :) If you use any programs that keep machine-dependant file formats (rrdtool data files, for example), export them to a portable format before the switch, and reimport them afterwards. When I was satisfied I had a stable system, I moved my 64-bit kernel into /boot/kernel, removed the kernel= line from boot.conf, promoted the cloned root.amd64 filesystem and destroyed the i386 root and the snapshot. -- Dan Nelson dnel...@allantgroup.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
