...I'm actually starting to think that Nexenta's /usr/sun isn't that bad an idea and maybe even Solaris should have that. That would mean that I could do things like this: PATH=/usr/sun/bin:/usr/gnu/bin:/usr/bin That would mean that on Nexenta and on Solaris I would always prefer the 'Solaris/Sun' version of a tool over the GNU one then what ever is in /usr/bin. Or I could do: PATH=/usr/xpg6/bin:/usr/gnu/bin:/usr/bin Which would mean prefer 'POSIX' then GNU then what ever the host has. For Solaris /usr/sun would probably be links to /usr/bin and the /usr/gnu/bin stuff would binaries. For Nexenta the /usr/gnu/bin would be links to /usr/bin and the /usr/sun/bin would be the binaries. For me all that appears to me missing on Solaris is /usr/gnu and /usr/sun and for Nexenta adding the /usr/xpg? variants. A distro should be free to not provide any of the /usr/xpg?, /usr/sun or /usr/gnu personalities if it doesn't want to. IMO these personality directories should only be used where there are multiple incompatible implementations of a command/library of the same name. For example smbclient should always be in /usr/bin since there is only one smbclient. Same for ncftp(1) there is only one ncftp(1). On the other hand I'd expect an ls(1) command in everyone of those directories.
Hmm, nice synthesis. So is the following a logical conclusion? With a fairly painless change to the /usr/gnu ARC proposal[1], we can achieve a compatibility alignment in this regard between Nexenta, Solaris Express (Nevada), and any other distros that also align...
