FACT-1804

I just did a recursive grep; the value does not appear anywhere under /proc. Nor is uname helpful:

$ uname -a
Linux koji-b3-f27.doubledog.org 4.13.16-302.fc27.armv7hl #1 SMP Thu Nov 30 16:57:55 UTC 2017 armv7l armv7l armv7l GNU/Linux

I can only guess at the intentions of design for yum. But I suspect the reason their $basearch differs from fields in uname was to minimize duplicate packages across repositories for otherwise compatible architectures. If it helps, there's this snippet from /usr/lib/python2.7/site-packages/rpmUtils/arch.py of yum-3.4.3-513.fc27.noarch that I think explains much:

def getBaseArch(myarch=None):

    """returns 'base' arch for myarch, if specified, or canonArch if not.

       base arch is the arch before noarch in the arches dict if myarch is not

       a key in the multilibArches."""

    if not myarch:

        myarch = canonArch

    if myarch not in arches: # this is dumb, but <shrug>

        return myarch

    if myarch.startswith("sparc64"):

        return "sparc"

    elif myarch == "ppc64le":

        return "ppc64le"

    elif myarch.startswith("ppc64") and not _ppc64_native_is_best:

        return "ppc"

    elif myarch.startswith("arm64"):

        return "arm64"

    elif myarch.startswith("armv6h"):

        return "armhfp"

    elif myarch.startswith("armv7h"):

        return "armhfp"

    elif myarch.startswith("arm"):

        return "arm"

    if isMultiLibArch(arch=myarch):

        if myarch in multilibArches:

            return myarch

        else:

            return arches[myarch]

    if myarch in arches:

        basearch = myarch

        value = arches[basearch]

        while value != 'noarch':

            basearch = value

            value = arches[basearch]

        return basearch
