| Can someone tell me where /etc/init.d/hostname script (when run at boot) gets the domain name from? |

IMHO wrong.
I've : | Code: | tfoerste@n22 ~ $ cat /etc/conf.d/hostname
# Set to the hostname of this machine
hostname="n22"
|
and /et/issue shows my domain name if I use "\O" instead the default "\o"[code]:[code]tfoerste@n22 ~ $ cat /etc/issue
This is \n.\O (\s \m \r) \t
[/code] |

The Gentoo Handbook specifies /etc/conf.d/hostname as the place. If /bin/hostname doesn't show the same hostname after /etc/init.d/hostname is invoked, then that's a bug.
It is true that \O in /etc/issue displays the FQDN, and not just the hostname. This is equivalent to "hostname -f" .

That documents says : | Quote: | | Second, if you need a domainname, set it in /etc/conf.d/net. |

| Every script from /etc/init.d inherits the variables set in /etc/conf.d/$same_name. Whether it uses these variables depends on the script, but an inspection of /etc/init.d/hostname shows that this script obviously uses the variable defined there for the call of the hostname binary. |

That is also where I set my domain name.
| Quote: | | hostname="Myhostname.mydomain" |
However, I see when I start up, my logon prompt says:
This is user at Myhostname.mydomain.mydomain
(or something to that effect, I don don have access to that pc now.
So I guess there is still a second location where the domain name is set, or it is reinterpreted a second time.
however, the only place where I explicitly mention the domain name is in the dnsmasq configuration (this PC is acting as a router).
DNSMASQ_OPTS="$DNSMASQ_OPTS --domain-needed --domain=mydomain" |

Try to set your domain name in /etc/hosts
Something like
| Code: | 127.0.0.1 hostname.domainname hostname localhost

In /etc/hosts you should have something like...
| Code: | | 192.168.0.1 hostname.domain.com hostname |
...obviously replacing hostname and domain.com with whatever you are using. |
