# This file aggregates all environment variables into one file. Customarily,
# Gentoo disaggregates all environment variables into the "/etc/env.d/" path,
# from which it then dynamically constructs the "/etc/profile.env" file, which
# this file sources. I find that to be a rather clumsy and overly abstracted
# means for defining environment variables, however; I prefer this.

# Load environment settings from profile.env, which is created by
# env-update from the files in /etc/env.d

# There's no real reason to exclude sbin paths from the normal user,
# but it can make tab-completion easier when they aren't in the

# It is intentional in the following line to use || instead of -o.
# This way the evaluation can be short-circuited and calling whoami is
