After updating coreutils, I got: "Detected file collision(s): * /usr/bin/arch * /usr/share/man/man1/arch.1.bz2", i.e. both packages install /usr/bin/arch and the corresponding man files. "portageq owners / /usr/bin/arch" gives: sys-apps/util-linux-2.12r-r8 /usr/bin/arch sys-apps/coreutils-6.10-r1 /usr/bin/arch Reproducible: Didn't try
if your system wasnt outdated, this wouldnt be a problem ... util-linux-2.13 doesnt provide arch anymore
