We package the lockdown-support.sh script from Purism's librem5-base package. This script has a bash shebang[1] and so won't work with any other shell. It also uses some bashisms that Ash doesn't support, so we can't just change the shebang to be /bin/sh or such as that will break the script. As such, just solve this in the simplest way for now and depend on bash. If someone feels motivated to replace the bashisms in the upstream script they're very welcome to do so.
