I have been using ext2fs for ages under FreeBSD. The support is smooth and reliable. All you need to do is kldload linux. ext4 works under FreeBSD via fuse-ext2, which unfortunately is quite slow as on date. ZFS, as you correctly point out, is another option that I will keep in mind in future. Thanks, Manish Jain
