Thank you, Lowell. For your extremely informative reply. Curious. The man page I read from my freshly built 11-CURRENT indicates the following:
xz:compression-level A decimal integer from 0 to 9 specifying the xz compres- sion level. As I have always read that (interpreted it). It meant: xz:<decimal-number> (0-9) Which is what I've always used. I haven't grepped ports||src yet. But if it makes any difference, it came from src -- build/install world. I'll do some poking around. But all my other boxes (RELENG_8 && RELENG_9) use xz:<decimal-number>. Thanks again, Lowell. For taking the time to respond.
