Hello,
I keep getting messages from syslog "key "cdrom" not found in map source(s)." on the console of my Debian Stretch system but I don't even have a cd rom installed in this system.
I already checked /etc/fstab, /etc/samba/smb.conf, /etc/autofs.conf and all the /etc/auto.* files as this message normally points to wrong NFS or other file system exports. I also checked the output of exportfs and did reboot many times but I can't get rid of these messages.
Do you have any idea what else could cause them?
Best regards,
Reiner
