And understand a bit of the history. Maybe AIX has df -g because of it's
BSD affinity that goes back a long, long time.
AIX does have a -g option for du.
And now that I have been reading configure --help, I may just remove df/du
from the coreutils I package (and figure out a way to supply them as an
optional addition) using --enable-no-install-program="df,du". This will
certainly resolve my problem with wanting to use df -g nad having to type
/us/bin/df -g to get it when I need it. :)
