Hi,

I finally found the culprit:

There udev-related files under /lib, where I did not search for it.
I had expected them under /etc...
I fixed one of the rules and now there is the correct link.

Nonetheless, ls -l /proc shows:
beagleboneblack:/root>ls -l /proc

There are still files stamped with the UNIX's big bang moment.
But the kernel is configured to use rtc1 instead of rtc0.

The journey isn't at its end, still.

ANy further ideas ?
