Hi Luca, all,
I'd be happy to work on putting the changes back in
package/bash/bash_profile. I've only used default
packages/configurations in Buildroot so I'm not very familiar with
modifying them, and I could use some guidance. Should I place
bash_profile in package/bash and then have the bash package Makefile
copy it to system/skeleton/etc/profile? Or is there another way I
should install it?
David
