If we can avoid them, yes. The stuff we absolutely must not have is: * bashisms in scripts that start with #!/bin/sh as opposed to #!/bin/bash (and for scripts that are installed on the target we try to avoid the latter as it just means bash has to be installed on the target as well, which is often not desirable) * bashisms in shell functions within recipes since these are executed under /bin/sh Even if we were to ignore alternative shells such as zsh and tcsh, bashisms in the above cases will cause breakages on Ubuntu (where /bin/sh is dash by default). From the denzil (Yocto Project 1.2) release onwards we have been stamping out bashisms and trying to avoid introducing any new ones.
