Should node-red recipe depend on both of bash and zsh?

[cosmo0920]

Hi, I've hit an unexpected running update-alternative hook for zsh when installing node-red which is built with meta-nodejs-contrib.

Environment Description

I'm working on bash shell based BSP which is for Renesas RZ/G1 board Yocto 2.0.
This board does not provide zsh compatible PS1:

/etc/profile

# <snip>
if [ "$PS1" ]; then
# works for bash and ash (no other shells known to be in use here)
   PS1='\u@\h:\w\$ '
fi

Expected Behavior

When installing node-red yocto built package, update-alternative hook for zsh does not work and still be able to use bash as /bin/sh.

Actual Behavior

update-alternative hook for zsh works and replace /bin/sh/ with /bin/zsh.
