Bug#744365: lb config does not create "config" directory

[Karsten Merker <merker@debian.org>]

Package: live-build
Version: 4.0~alpha33-1
Tags: patch

Hello,

running "lb config" from the current unstable live-build package
(4.0~alpha33-1, identical to current git as of commit
145418141e4965691dad1757c6fbdffa4a96290c) in an empty directory
results in

    P: Creating config tree for a debian/wheezy/amd64 system
    /usr/lib/live/build/config: 892: /usr/lib/live/build/config: cannot create config/common: Directory nonexistent

The code fragment responsible for this is:

    884 if [ ! -e config ]
    885 then
    886         Echo_message "Creating config tree for a ${LB_MODE}/${LB_DISTRIBUTION}/${LIVE_IMAGE_ARCHITECTURE} system"
    887 else
    888         Echo_message "Updating config tree for a ${LB_MODE}/${LB_DISTRIBUTION}/${LIVE_IMAGE_ARCHITECTURE} system"
    889 fi
    890 
    891 # Creating live-build configuration
    892 cat > config/common << EOF

The "if" clause in line 884 checks for the existence of the config
directory, but does not create it when missing, so trying to
create config/common in line 892 fails when running "lb config"
without an existing config directory.  The following one-line
patch fixes that.
