dd 2001/11/24 07:34:18 PST Modified files: sys/dev/snp snp.c Log: Return EBUSY if we try to attach to a tty that is already being snooped on. This causes all kinds of Bad Things(tm) to happen since closing one session will clobber state that's needed for the other one. This could theoretically be supported if the code was careful, but until somebody implements that, preventing this will stop people from unknowingly shooting themselves in the foot.
