Why would we want to use /usr/bin ? According to https://docs.oracle.com/cd/E19253-01/816-5175/standards-5/index.html ---8<--- Utilities If the behavior required by POSIX.2, POSIX.2a, XPG4, SUS, or SUSv2 conflicts with historical Solaris utility behavior, the original Solaris version of the utility is unchanged; a new version that is standard-conforming has been provided in /usr/xpg4/bin. If the behavior required by POSIX.1–2001 or SUSv3 conflicts with historical Solaris utility behavior, a new version that is standard-conforming has been provided in /usr/xpg4/bin or in /usr/xpg6/bin. If the behavior required by POSIX.1–2001 or SUSv3 conflicts with POSIX.2, POSIX.2a, SUS, or SUSv2, a new version that is SUSv3 standard-conforming has been provided in /usr/xpg6/bin. ---8<--- So we should obviously make sure to prefer /usr/xpg6/bin over /usr/xpg4/bin over /usr/bin. If we don't then i would say that's the bug to fix, not warp back in time 20 years. Why let solaris hold hostage everybody else? thanks,
