when /etc/hostname is empty or missing 'localhost' not properly set as the hostname

[Ricardo Sanchez]

If the file /etc/hostaname is empty or missing, the hostname is not properly set. This causes problems with the sudo version present in 6.06 (error message: sudo: unable to lookup hola via gethostbyname()). I think the sudo present in 6.10 fixed this.

Anyway, to fix the problem to the root, the file /etc/init.d/hostname.sh has to be modified, and the following lime must be added.

root@localhost:/etc/init.d# diff hostname.default.sh hostname.sh -c

*** hostname.default.sh 2007-02-08 17:38:31.000000000 +0100
--- hostname.sh 2007-02-08 17:23:36.000000000 +0100
***************
*** 23,28 ****
--- 23,29 ----

        # And set it to 'localhost' if no setting was found
        [ -z "$HOSTNAME" ] && HOSTNAME=localhost
+ [ "$HOSTNAME" == "(none)" ] && HOSTNAME=localhost

        [ "$VERBOSE" != no ] && log_action_begin_msg "Setting hostname '$HOSTNAME'"
        hostname "$HOSTNAME"

1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.

2. Please run the command "dpkg -l | grep initscripts" and post the result to this bug report.
