I was really shocked when I tried to upgrade from High Sierra to Mojave about a month ago and found that my work directory was completely gone. It turned out that I rigged the work directory to Dropbox via a hard link, which is emulated in HFS+ as a shadow directory plus a placeholder, and the conversion to APFS broke this emulation. Fortunately for me I had a shortcut to that shadow directory in the Finder and was able to recover it, this time using a plain symlink (less than ideal, sigh), but I now have a big question about Apple concerning about existing users. At least I trust Dropbox more than Apple though...
