turn compression on.
segment shift in bits.
write shift in bits.
skip bad block scan; don't erase device.
turn off safety question before writing.
Segment size and write size are powers of two. To specify them, the appropriate power is specified with the "-s" or "-w" options, instead of the actual size. E.g. "mklogfs -w8" will set a writesize of 256 Bytes (2^8).
