I got an error message like the following:

Jan  7 12:13:52 myhost nsd[92737]: corrupted database: /var/db/nsd.db
Jan  7 12:13:52 myhost nsd[92737]: unable to load /var/db/nsd.db: No such file or directory

The reason is the inconsistency between NAMEDB_MAGIC embeded
in nsd.db and one nsd can treat. For example, nsd.db
geterated by zonec in has "NSDdbV5" as NAMEDB_MAGIC and feed
it to nsd 2.1.2 makes the matter described above because nsd
2.1.2 only accept "NSDdbV6".

The erroe message "corrupted database" is easy to
understand, but "No such file or directory" makes me be
confused, yes, the file IS.

This message is came from strerror() called by server_init()
in server.c. But in this case, system call isn't involved
with the error, so to call strerror() sounds inapropriate, I
