Duplicate entries in $profile/etc/profile

Duplicate entries in $profile/etc/profile

[Andy Wingo]

Hi,

With this manifest:

    (use-package-modules gcc llvm base python version-control less ccache)

    (packages->manifest
     (list clang
           coreutils
           diffutils
           findutils
           tar
           patch
           sed
           grep
           binutils
           glibc
           glibc-locales
           which
           gnu-make
           python-2
           git
           less
           libstdc++-4.9
           gcc-4.9
           (list gcc-4.9 "lib")
           ccache))

If I install these packages via:

  guix package -p ~/profiles/v8 -m ~/profiles/v8.scm

And then:

  cat ~/profiles/v8/etc/profile

I get:

    # Source this file to define all the relevant environment variables in Bash
    # for this profile.  You may want to define the 'GUIX_PROFILE' environment
    # variable to point to the "visible" name of the profile, like this:
    #
    #  GUIX_PROFILE=/path/to/profile
    #  source /path/to/profile/etc/profile
    #
    # When GUIX_PROFILE is undefined, the various environment variables refer
    # to this specific profile generation.

    export PATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/bin:${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/sbin${PATH:+:}$PATH"
    export CPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/include${CPATH:+:}$CPATH"
    export LIBRARY_PATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib${LIBRARY_PATH:+:}$LIBRARY_PATH"
    export LOCPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib/locale${LOCPATH:+:}$LOCPATH"
    export PYTHONPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib/python2.7/site-packages${PYTHONPATH:+:}$PYTHONPATH"
    export CPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/include${CPATH:+:}$CPATH"
    export LIBRARY_PATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib${LIBRARY_PATH:+:}$LIBRARY_PATH"
    export CPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/include${CPATH:+:}$CPATH"
    export LIBRARY_PATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib${LIBRARY_PATH:+:}$LIBRARY_PATH"
    export CPATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/include${CPATH:+:}$CPATH"
    export LIBRARY_PATH="${GUIX_PROFILE:-/gnu/store/v18xavw7q79rbg0ly697d7q5as785rir-profile}/lib${LIBRARY_PATH:+:}$LIBRARY_PATH"

Which obviously includes three identical copies of CPATH and
LIBRARY_PATH.  What's up with that?

Duplication comes from the fact that 3 entries in the manifest claim
these two variables: clang, gcc, and gcc:lib.

In this case all three search path specifications are identical, so this
is harmless.  Commit fa96048 fixes that.

To be complete, we should perhaps warn the user when different
specifications are given for the same variable.  That seems rather
unlikely, though.

Thanks for the report!
