  • [gentoo-dev] [PATCH] profiles: workaround sandbox bug with getcwd() con

    From Sam James@21:1/5 to All on Mon Jan 22 17:20:01 2024
    Workaround for sandbox bug which causes this gnulib configure test to take
    many real hours on slower machines, and certainly a huge amount of CPU hours
    on others.

    Spoof the same result as configure gets on a modern glibc & musl system for now.

    Bug: https://bugs.gentoo.org/447970
    Closes: https://bugs.gentoo.org/922652
