Calling link(2) with a symlink as the target will cause FreeBSD to attempt to create a new hard link pointing to the target of the symlink rather than a hardlink to the symlink itself. By contrast, Linux creates a hardlink to the symlink. Use linkat(2) instead, which accepts a flag controlling this behavior. If linkat(2) is called with AT_SYMLINK_FOLLOW, it will behave the same as link(2). If linkat(2) is called without AT_SYMLINK_FOLLOW, it will behave the same as Linux's link(2) instead. See FreeBSD's implementation of ln(1), which uses linkat(2) and controls this behavior by way of the -P and -L flags: https://github.com/freebsd/freebsd-src/blob/30031172534c22695ab7b26a9420bda7b20b0824/bin/ln/ln.c#L342-L343 Signed-off-by: Samuel Karp <me@samuelkarp.com>
