Stracing tapisrv and postprocessing the capture to have a more readable log.

Set LOGFILE and lauch strace with this command:

$ strace -v -f -F -tt -xx -s 2048 -o $LOGFILE -p `pidof tapisrv` &

and run:

$ ./tapisrv_strace_postprocess.sh $LOGFILE

You could also exploit linloader, try the provided files in ./temp dir.

To have a capture of commands issued at early boot you could dump the rootfs,
wrap the tapisrv binary (renaming it) with a script that invokes strace (with
output directed to a writeable location), and reflash the rootfs image.
