This means that 149.Xr strings 1 150can be used to extract it from a kernel. 151.Pp 152Strings | grep ___ will print just the configure information. 153.Sh FILES 154.Bl -tag -width /sys/i386/conf/Makefile.i386 -compact 155.It Pa /sys/conf/files 156list of common files system is built from 157.It Pa /sys/i386/conf/Makefile.i386 158generic makefile for the 159.Tn i386 160.It Pa /sys/i386/conf/files.i386 161list of 162.Tn i386 163specific files 164.It Pa /sys/i386/conf/devices.i386 165name to major device mapping file for the 166.Tn i386 167.It Pa /sys/i386/conf/files.
