[Hostname-devel] Bug#650822: hostname set hostname to (none)

[Elvir Kuric]

Package: hostname
Version: 3.04
Severity: normal


In case there is space at end of hostname name in /etc/hostname,the hostname
will be set to (none) after next boot

If space is present at end of line in /etc/hostname,then /etc/init.d/hostname.sh 
will report 

# /etc/init.d/hostname.sh
hostname: the specified hostname is invalid
 
Possible solution: 

In /etc/init.d/hostname.sh is there in function do_start()

do_start () {

        [ -f /etc/hostname ] && HOSTNAME="$(cat /etc/hostname)"

--- (rest of hostname.sh) --- 
       
If  

	[ -f /etc/hostname ] && HOSTNAME="$(cat /etc/hostname)"

is changed to 

 [ -f /etc/hostname ] && HOSTNAME="$(cat /etc/hostname | sed 's/^[ \t]*//;s/[ \t]*$//')"
  

then trailing space in line in /etc/hostname will be removed,and /etc/init.d/hostname.sh will
not report above error
