Description Ulenrich 2017-08-19 12:14:05 UTC

If run emerge python ebuilds on a tmp filesystem, like df:
tmp                     2097152     24740   2072412   2% /tmp
then pax marking won't work for all python builds:
---
 * Messages for package dev-lang/python-2.7.13:
 * Failed to set XATTR_PAX markings -me python.
 * Messages for package dev-lang/python-3.5.3:
 * Failed to set XATTR_PAX markings -me python.
 * Failed to set XATTR_PAX markings -me /tmp/portage/dev-lang/python-3.5.3/image/usr/bin/python3.5m.
 * Messages for package dev-lang/python-3.6.1-r1:
 * Failed to set XATTR_PAX markings -me python.
 * Failed to set XATTR_PAX markings -me /tmp/portage/dev-lang/python-3.6.1-r1/image/usr/bin/python3.6m.

but if moving the portage to hard disk it will work.
