If PORTAGE_TMPDIR="/" , it will create /portage folder, but emerge --resume will not accept it the second time it is run. emerge --resume Calculating dependencies... done! *** Resuming merge... >>> Verifying ebuild manifests >>> Emerging (1 of 1) dev-qt/qtwebengine-5.11.3::gentoo >>> Jobs: 0 of 1 complete, 1 running Load avg: 1.39, 0.98, 0.88 !!! The 'portage' subdirectory of the directory referenced by the !!! PORTAGE_TMPDIR variable appears to be a symlink. In order to avoid !!! sandbox violations (see bug #378379), you must adjust PORTAGE_TMPDIR !!! instead of using the symlink located at '/portage'. A suitable !!! PORTAGE_TMPDIR setting would be '/portage'. If PORTAGE_TMPDIR="/portage" it will create /portage/portage and not give this error.
The message was intended to reference bug 378403.
It's not enough to change path comparison logic in https://gitweb.gentoo.org/proj/portage.git/commit/?id=8a85160f4833e3f02470961fc2e05ec93f466566, because with PORTAGE_TMPDIR=/ the sandbox configuration actually allows unrestricted write access to all paths.

Also, remove the _check_temp_dir symlink check from bug 378403, since a symlink is permissible if write access is granted directly to ${PORTAGE_TMPDIR}/portage.
