A restrictive mask of 0027 will make genkernel-next install the kernel with this umask. virtualbox-modules will fail to install since it cannot access several file in the /usr/src/linux or /lib/modules Reproducible: Always Steps to Reproduce: 1. umask 0027 2. install a kernel using genkernel-next 3. emerge -va virtualbox-modules Actual Results: >>> Emerging (1 of 2) app-emulation/virtualbox-modules-5.0.0::gentoo * Fetching files in the background.

is this still valid with version 64?
No time to try it. Changed to resolved.
