Operating Systems Linux Fedora Clueless re Java: /opt vs. /usr/local Post 302879799 by fpmurphy on Sunday 15th of December 2013 11:46:03 AM

A word of caution regarding the FHS. It is quite an old document. Many distributions, led by Fedora, are moving away from this standard as far as /usr/bin, /bin, /usr/sbin, /sbin and other OS-specifc directories are concerned.

However the intended purpose for /usr/local and /opt has not changed over the years.
