Debian 12 doesn´t include the /etc/updatedb.conf file. I use locate to find things in /mnt. This needs a modified PRUNEPATHS declaration, so I copied an /etc/updatedb.conf which doesn´t prune /mnt from a Debian 11 installation.
I am surprised to see no /etc/updatedb.conf in Debian 12. Is this deliberate? The man (5) page for updatedb.conf is also missing. Roger
