Based on the man page of the command "updatedb", we can change and override the configuration of /etc/updatedb.conf using the below commands:
--prune-bind-mounts FLAG Set PRUNE_BIND_MOUNTS to FLAG, overriding the configuration file. --prunefs FS Set PRUNEFS to FS, overriding the configuration file. --prunenames NAMES Set PRUNENAMES to NAMES, overriding the configuration file. --prunepaths PATHS Set PRUNEPATHS to PATHS, overriding the configuration file.
But when I try to use them, there is no change. For example I expect the command below to change the flag to "no", but nothing happens:
sudo updatedb --prune-bind-mounts no
Just it takes a while to execute and exits without any warnings or errors, when I check the /etc/updatedb.conf content, it's the same as before.
