Error build image (at bootlogo)

[-M-]

I'm new with OpenViX and have been able to build it. However not on first try, I got a problem. Bash extension is used in the openvix-bootlogo.bb file. The script code from the bb files are used in sh-scripts, not bash-scripts. So for example on Ubuntu, the script will fail if bash extension is used.

I solved it by this:

diff --git a/meta-oe/recipes-distros/openvix/image/openvix-bootlogo.bb b/meta-oe/recipes-distros/openvix/image/openvix-bootlogo.bb
