Hi Richard,
The definitive answer is in the dhcp-options man page:
REFERENCE: OPTION STATEMENTS
The text data type specifies an NVT ASCII string, which must be
enclosed in double quotes - for example, to specify a root-path option,
the syntax would be
option root-path "10.0.1.4:/var/tmp/rootfs";
and further down that same document
TEXT
option new-name code new-code = text ;
An option whose type is text will encode an ASCII text string.
For example:
option sql-default-connection-name code 194 = text;
option sql-default-connection-name "PRODZA";
regards,
Glenn
