Thank you for the new version!
It looks good to me, but again, my review mainly focused on the
Bash-related stuff, not on the netconsole test itself.
I just have one question below, but not blocking.

It looks like your 'check_file_size' helper is a reimplementation of
'test -s <FILE>', no? Can you not simply use:
busywait "${BUSYWAIT_TIMEOUT}" test -s "${OUTPUT_FILE}"
Apart from that, the rest looks good to me!
