Yes.  All of the functions that write data end up calling the
dump_write() function, which will fail if an attempt is made to write
outside the dump device. In addition, the code does a preliminary
compress to determine where it should start writing the dump.  If that
size is larger than your dumpdevice, it will print a "Dump failed.
Partition too small." error and won't write to disk at all.
