Hi, I usually have `umask 077` set for all my users, everything works fine until I try to emerge virtualbox. This happens because the kernel is compiled using that umask and virtualbox spawns that error. I'm not sure if I should have assigned it to you, but is there any way we can avoid this to happen? >>> Emerging (1 of 1) app-emulation/virtualbox-modules-4.2.18 * vbox-kernel-module-src-4.2.18.tar.xz SHA256 SHA512 WHIRLPOOL size ;-) ...

As far as I know this issue started with virtualbox 4.2.18 only. Had no problems like that up until 4.2.16.
Are we sure this is a new issue with virtualbox, and not a result of the new portage default of FEATURES=userpriv? If you disable userpriv or allow the kernel sources to be portage:portage readable, does the build succeed?
Ben that is correct, if I disable userpriv everything compiles fine. If anyone else finds this bug, until it's fixed, (re)compile your kernels under `umask 022` (at least) or disable FEATURES=-userpriv
@dev-portage could you give your opinion on this? FEATURES=userpriv shouldn't bring, as far as I understand, this type of error as the files are indeed readable by portage (-rw-r--r--). Is this a virtualbox issue or a portage one?
Okay, this seems to be an invalid bug, or better said, a picnic issue. Using umask 077 (or anything that does not allow (at least) read permission to the portage group) for compiling the kernel is a user problem, not a portage nor virtualbox one. Apologies.
