How to suppress the error message "no such device" during execution of a configuration file

[Arbiel Perlacremaz]

Hi

I wrote a configuration file which looks for a particular device where a given partition has been defined

search --label --no-floppy set=root label

When root is not set after this command, the configuration file loops on
 a read command, until the entry is empty or the partition is found.

So, I would be glad to suppress the "no such device" message

How can this be done ?

Thank you for any piece of advice
