That's fine. wether the future version starts life as star, gtar, futar, or tar, doesn't matter. > If you like the features from other tar implementation from a program > called 'tar' you will get into trouble as this is not really possible with > a program that uses a legacy CLI from the 1970s.

Again, tar is just one example of a program which already has multiple binaries floating around and something people expect to be on the system. -- Alan DuBoff - Sun Microsystems Solaris x86 Engineering _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
