No, not yet. I do use in layout.conf
profile-formats = portage-2 profile-bashrcs profile-set
profile-bashrcs perhaps?
I just did a
egencache --update --update-use-local-desc --update-pkg-desc-index
for all repos on that system and it is still there.
Then I recalled portage renames my repo to x-portage so I tried
egencache --update --update-use-local-desc --update-pkg-desc-index --repo
x-portage
but that did not help either.
