=sys-apps/portage-2.2_rc33 in defines PATH likes this:


Is there any real reason to keep /bin and /sbin before /usr ones? In my opinion, /usr/*bin should be placed before /*bin in $PATH.

Firstly, /*bin can contain some kind of stripped down versions of utilities which doesn't require /usr to be mounted. And then /usr/*bin would contain full-featured versions which should be used instead if /usr is available.

Secondly, this $PATH already contains /usr/local/*bin before /*bin and thus allows user to override root binaries with /usr/local ones. To keep the hierarchy clean we should allow /usr ones to override them too.

Moreover, this is the way /etc/profile by default (=baselayout-2.0.1) defines PATH. Thus, if there's no real reason to keep /*bin before /usr/*bin in portage-defined PATH, I think the PATH definition should be modified to:
