My understanding of /bin vs. /usr/bin is that /bin should contain the
binaries needed for booting the system, as well as a base set of utilities
needed by all users (ls, chmod, etc.). /usr/bin should contain all the
rest. Taken that getfacl/setfacl functionally belongs in the same group
functionally as ls/chmod, I'd opt for /bin. I wouldn't think Solaris is a
good reference for utility locations. There is a filesystem hierarchy
standard, <http://www.pathname.com/fhs/>, though.
