Public bug reported:
Binary package hint: hostname
According to 'hostname --help', invoking hostname as domainname should
display the NIS/YP domain name, instead the host name is displayed.
Transcript follows:
$ hostname
dreamcoat
$ hostname -y
che.uct.ac.za
$ ln -s /bin/hostname domainname
$ ./domainname
dreamcoat
Output of 'hostname --help':
$ hostname --help
Usage: hostname [-v] {hostname|-F file} set host name (from file)
domainname [-v] {nisdomain|-F file} set NIS domain name (from file)
hostname [-v] [-d|-f|-s|-a|-i|-y] display formated name
hostname [-v] display host name
hostname -V|--version|-h|--help print info and exit
dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y
-s, --short short host name
-a, --alias alias names
-i, --ip-address addresses for the host name
-f, --fqdn, --long long host name (FQDN)
-d, --domain DNS domain name
-y, --yp, --nis NIS/YP domain name
-F, --file read host name or NIS domain name from given file
This command can get or set the host name or the NIS domain name. You can
also get the DNS domain or the FQDN (fully qualified domain name).
Unless you are using bind or NIS for host lookups you can change the
FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
part of the FQDN) in the /etc/hosts file.
As some commercial packages expect the NIS/YP domain name, I suggest
inserting the following lines in hostname.c:
if (!strcmp(progname, "domainname"))
type = NIS;
immediately below the lines:
if (!strcmp(progname, "dnsdomainname"))
type = DNS;
Alternatively, the help text should be updated to match the current
behavior.
