On the subject of bashisms, here are some hits in the current Sid version:

$ checkbashisms `grep -rl '#!/bin/sh' live-helper-1.0~a34/ live-initramfs-1.110.5/ `
possible bashism in live-helper-1.0~a34/functions/help.sh line 21 (echo -e):
                echo -e "${USAGE}"
possible bashism in live-helper-1.0~a34/functions/breakpoints.sh line 17 (read without variable):
                read
possible bashism in live-helper-1.0~a34/helpers/lh_binary_usb-hdd line 160 (read without variable):
        echo "WAITING..." && read
possible bashism in live-initramfs-1.110.5/bin/live-snapshot line 86 (echo -e):
                echo -e "${MESSAGE}"
possible bashism in live-initramfs-1.110.5/bin/live-snapshot line 104 (echo -e):
    echo -e "\nLook at live-snapshot(1) man page for more information."

Probably these should be "read dontcare" and "/bin/echo -e".
