hostname issues

hostname issues

[Andreas Müller]

Hi,

for xfce-session we have some very bad workaround entering machine
name to /etc/hosts [1]

I looked into this and found (let's assume ${MACHINE}='foomachine'):

* basefiles: By default /etc/hostname contains 'foomachine'
* netbase: /etc/hosts contains '127.0.0.1    localhost.localdomain
   localhost'

Shouldn't this be

/etc/hosts: '127.0.0.1    foomachine        localhost'
or
/etc/hostname: 'localhost.localdomain'

To test do

'ping foomachine'
or
hostname -f

What do experts say?

I'd suggest just installing nss-myhostname for sysvinit, and for systemd,
systemd already includes the myhostname nss plugin, so it just needs
enabling in nsswitch.conf (I submitted a patch recently to make it do that
by default).

Thanks a lot - that looks promising. Will give the systemd nss path a
test with your patch.
