I'm curious what people regard as the best way to override standard 
system executables with local versions or versions from pkgsrc.

Just installing things in /usr/pkg/bin or /usr/local/bin runs afoul of 
the default PATH -- those follow /bin and /usr/bin.  Change the default 
path in login.conf?  Is that the only place $PATH is set from?  Change 
things in per-user .profile?  That isn't executed during ssh, I believe.

Deleting or chmoding the standard executables is causes problems for
upgrades. 

Other choices?  (Weird games with overlay file systems in the Plan 9 
style?)
