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: (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:. Thanks again, Lowell. For taking the time to respond. Greatly appreciated. --Chris > > Good luck. > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" >
