86
87## The DDB in-kernel debugger runs at panic (unless DDB_ONPANIC=0), or at
88## serial console break or keyboard reset, where the PROM would normally
89## intercept.  DDB_HISTORY_SIZE adds up/down arrow command history.

93
94## You may also use gdb, on another computer connected to this machine over
95## a serial port.  Both KGDB_DEV and KGDB_DEVRATE should be specified;
96## KGDB_DEV is a dev_t encoded device number of the serial port to use.
97## (0xc01 = ttya, 0xc02 = ttyb.)
98#options 	KGDB			# support for kernel gdb

110## cause the kernel to panic if corruption of internal data structures
111## is detected.

124## This allows writing to /dev/mem, loading kernel modules while multi-user,
125## and other insecurities good only for development work.  Do not use this
126## option on a production machine.
127options 	INSECURE
128
129## `FDSCRIPTS' allows non-readable but executable scripts by providing a
130## pre-opened opaque file to the script interpreter.  `SETUIDSCRIPTS',
131## which implies FDSCRIPTS, allows scripts to be set-user-id using the same
