[chef] bash -c '...' in bootstrap templates

[Maciej Pasternacki < >]

Hi,

I have noticed that all knife bootstrap templates bundled with Chef are 
shell scripts wrapped in extra layer of "bash -c '...'". Can anybody 
here explain, what is the reason for this - some escaping magic I can't 
grasp now (it seems to just add one escape level, which rather makes 
problems than solves them), is it related to sudo, or is it just to 
make sure that bash is used in case distro provides a different login 
shell?

Thanks,
