As suggested in Bug #125014 I unmerged pam-login. The merging process worked. But after upgrading, /bin/login was missing.
I don't know if this is related to this line from the sys-apps/shadow ebuild:
> # We do no longer install this one, as its from
> # pam-login now.
Anyway, I think you'll agree that this is actually /critical/.
Erm... You've been advised to unmerge pam-login *and* then update shadow, read Bug 126014, Comment #1 couple more times.
Sorry, PEBKAC is not a (Gentoo) bug.
Of course I DID remerge shadow -.-"
(In reply to comment #2)
> Of course I DID remerge shadow -.-"
re-emerge != update, please really read what you've been told.
Ok, got it. I think I rsync'ed at the wrong time or something. After another rsync, the shadow package 4.0.15 was no longer masked and this one worked.. So never mind. *sneaking away* *blush*
So, I hope it works for you now and this one can be closed... :=)
