[gentoo-alt] rap prefix - glibc-2.26-r3

[Steven Trogdon]

Hello,

Upgraded my prefix rap today doing:

emerge -1 portage
emerge -uDN system

I don't think the portage upgrade is the issue since the system proceeded to
upgrade, although with numerous warnings like:

portage: 'portage' user or group missing.
         For the defaults, line 1 goes into passwd, and 2 into group.
         portage:x:250:250:portage:/var/tmp/portage:/bin/false
         portage::250:portage
*** WARNING ***  For security reasons, only system administrators should be
*** WARNING ***  allowed in the portage group.  Untrusted users or processes
*** WARNING ***  can potentially exploit the portage group for attacks such as
*** WARNING ***  local privilege escalation.

I'm now unable to emerge anything. I think the culprit is the upgrade
of glibc from 2.25-r9 -> 2.26-r3 although it could be something else. Prior to
the upgrade getent <group | passwd> was parsing EPREFIX/etc/<group | passwd> for
group and passwd info. It clearly is now parsing /etc/<group | passwd>. And I
have no control over what is under /etc. In fact the host getent parses db
files in a non-standard location to get group/passwd info. When I attempt to
emerge I get things like

and the emerge fails.

From within prefix

From the host
id

Looking for things to try without re-installing prefix[rap].
