The first line of the list can be first_line_len characters long. @UnitedMarsupials, because leading whitespace has meaning in python and yaml files (and possibly other formats), I'd suggest using -Z (--ignore-trailing-space) instead of -b (--ignore-space-change).

This can be done using the start_block and This filter can be used to generate a random MAC address from a string prefix. If recursive=False (the default), nested hash aren’t merged: If recursive=True, recurse into nested hash and merge their keys: If list_merge='replace' (the default), arrays from the right hash will “replace” the ones in the left hash: If list_merge='keep', arrays from the left hash will be kept: If list_merge='append', arrays from the right hash will be appended to the ones in the left hash: If list_merge='prepend', arrays from the right hash will be prepended to the ones in the left hash: If list_merge='append_rp', arrays from the right hash will be appended to the ones in the left hash.
