I?m not 100% sold on that one way or another, but since I was going to redo the number representation in save core with humanize_number(3), because reading `KiB` is not ideal usability wise, and I don?t want to reinvent the wheel normalizing numbers and printing out the unit. > > *unit. ?> *unit, KiB seemed like a logical next step after discussing it at long length in the CR. I do not see any long length discussion in the CR. I see an assertion that KiB is the new IEC standard, I see a miss understanding of what kB and KB means, and I see someone wanting to push the tree towards IEC. I see here on the mailling list a push to NOT start IEC'ing things, at least by myself and jhb. I would not consider 2 or 3 peole have a 15 line converstaion in a CR as reasonable grounds for a change like this. -- Rod Grimes rgrimes@freebsd.org
