Is there a limit to the number of domain names listed in the search
parameter for the resolv.conf file? I have a network monitoring
application monitoring different customer environments, and I wish to
use the ordinary name instead of the fully qualified domain name (FQDN).
I have 10 different customer second level domains, and I will add all 10
too the search parameter. I have not found any documentation which
identifies a limit to the number of domains listed on the search
parameter in the resolv.conf file. The network monitoring applications
reside on Linux, Solaris, and HPUX. I appreciate any input!

obviously you didn't look really hard .. `man resolv.conf` on
Solaris 2.6/7 tells:

The search list is currently limited to six
domains with a total of 256 characters.

it also tells you that it might not be a good idea to use a very
long search list, regarding performance.
