Comment 1 Jonas Stein gentoo-dev 2016-05-17 19:04:41 UTC
This problem does not occur on amd86.

I have no arm system available now, but other users on IRC could not reproduce this:
=======
i see -rw-r--r-- here
-rw-r--r--  1 root root    0 May  4 14:20 .keep_net-misc_ntp-0
checked on both a vanilla hardfloat and hardened hardfloat, identical
=======

What is your mount status?
May be it is easier to locate the problem via IRC or Forum.

Comment 3 Steev Klimaszewski (RETIRED) gentoo-dev 2016-05-17 21:18:11 UTC
I can't seem to replicate this here at all.  And there's nothing immediately apparent in your mounts that would cause this.
Comment 4 Alex Xu (Hello71) 2016-05-23 22:52:55 UTC
[23:15:39] < dwfreed|phone> it seems like his umask is set incorrectly
[23:17:54] < dwfreed|phone> definitely his umask, because that doesn't happen on my system
[23:23:26] < dwfreed|phone> also, portage does a lot of 'umask 022'
[23:27:05] < dwfreed|phone> Hello71: the dead giveaway should have been the keep files being world-writable
[21:41:52] < Hello71> dwfreed|phone: because there's seven of them. bulk close INVALID?
[21:49:50] < dwfreed|phone> Hello71: yes
