When running with --removable-device, the basename of dest is used to construct the path of the "removable" sysfs file for the device. However, if dest is a symlink the basename may be very different from the actual device name, and theoretically might even match a different device. Make the path absolute and resolve any symlinks before taking the basename to avoid that problem. This is of practical importance because it allows using /dev/disk/... symlinks created by udev, which is much less error-prone than using e.g. /dev/sdX.
