Learned something new today! Apparently, the ext2 & ext3 filesystems support this (not sure about others). The e2fsprogs package (this may be installed by default by your distro, but I think it was something I had to add manually in gentoo) includes two programs: lsattr and chattr which list and change ext2 & 3 specific attributes. I tried out the append-only flag, and it works! Neat!
