I have an amd64 which has been wholly 64-bit for some years, but it only has 1GB of memory and that is no longer comfortable for compiling recent firefox with recent gcc : everything keeps getting bigger and using more memory, so the box often swaps when compiling.
Personally, I suggest that you _consider_ the following partitions: (i) enough for fedora - no idea how much is "enough", but I would hope 10GB is plenty - best to check that first! It's certainly enough for LFS+BLFS. Also /boot if you intend to stay with LFS, and swap [ e.g. for s2disk even if you have enough RAM ]. (ii). a couple more partitions of the same 10GB size - this will allow you to build LFS+BLFS in one of them, for the other you can either build your *next* LFS there, or install a different distro. (iii.) Use whatever is left for /home, and share the user(s) and groups between fedora and LFS. Of course, if all you intend to do is build LFS once for the experience, then my partitioning suggestion won't be useful. Really, there is very little difference between i686 and x86_64 for LFS : x86_64 has more registers, so gcc tends to produce better code (more variables in registers), but with bigger pointers. For the LFS book, the differences with current software are minimal. For BLFS, almost everything in current use works with either architecture. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
