Subject: Ignore failure to set host name
X-Git-Url: https://git.siccegge.de//index.cgi?a=commitdiff_plain;h=a2198ae35b2ed0332580f11829a860ce9d31100d;p=forks%2Fvmdebootstrap.git

Ignore failure to set host name

At least minbase does not end up with an /etc/hosts file, so ignore
IOErrors for the hosts file.
