In bug 31877 we are disabling the pam_console module by default, that is,
pam_console is not used anymore to set the permissions on /dev nodes
automatically at login, instead we just rely on appropriate group permissions
on the devices.
In fact, newer versions of pam do not compile the pam_console module by default
anymore, so this change is already in effect now.
To complete the job, and for cleanness, you should remove the references to
pam_console.so in app-admin/conserver/files/conserver.pam*
Thanks.
IIRC pam_console itself is a linux-only solution... anyway, I don't know of
any subproject that is interested in keeping pam_console. It was switched off
for all archs in the tree when pam-0.78-r2.ebuild was keyworded.
