Title: Use fallocate instead of dd-ing zeroes if available

- there is no need to stress the harddrive/SSD and wait until half a
gigabyte of zeroes are written to a file
- since linux is assumed anyways, the linux specific fallocate call can
be used to allocate large files filled with zeroes in a few milliseconds
and without the need to write the zeroes manually
