Dear friends, When I run gem5 in full system mode with fs.py.    I find that the .rcS script given to --script doesn't work after system is booted. I can see 'readfile=/mydata/gem5/configs/boot/hack_back_ckpt.rcS'  line in config.ini. But why the command within it is ignored and doesn't work by gem5? I 've read all that question related to this on gem5 mailing list, but none of them give a feasible solution. What's wrong with these? Thanks, Yongjie
