scripts/check-config.sh exits successfully and silently without doing
any checks when the 'comm' command is not found.
The problem triggers from the command around line 39:
comm -23 ${suspects} ${ok} >${new_adhoc}
This statement fails when 'comm' is not in $PATH, creating an empty
${new_adhoc} file. But the script continues and the following line,
which is supposed to detect an error:
if [ -s ${new_adhoc} ]; then
will always be false since the file is empty, and the script will exit
successfully as if everything were OK.
The case where 'comm' in not in $PATH is not theoretical. It used to
happen on yocto until a recent fix [0], and still happens on the
current stable branch (rocko).
Fix by setting the errexit flag to exit with error when a statement
fails, so that at least the problem is noticed.
For additional safety also set the nounset flag to detect expansion
errors.
