Unfortunately, all other options (EnvironmentFile and pam_env) are
just too limited – none of them support even plain nesting of
variables (as in PATH=$HOME/bin:$PATH or
XDG_CONFIG_HOME=$HOME/.config).

I try to keep my ~/.environ clean of shell logic
(http://git.io/S0M_Sg), but I still cannot see myself giving up
`MAKEFLAGS=-j$(nproc)` or `source ~/.environ-$HOSTNAME`...

Not to mention that many packages install /etc/profile.d/ scriptlets
to set envvars the program depends on (JAVA_HOME, MOZ_PLUGIN_PATH, and
even LANG – which has to be set from profile because getty at .service
unsets it.)
