>Description:
In the file: /usr/src/sys/i386/boot/common/pnp.c, in the pnp_reload
function, at line 108, there is a bug: (by the way, this file hasn't got any
version info, it's on my 3.2-R i386 machine)
the function has only one parameter: the filename, (char *) fname; from which
file we need to reload some information. In the function, there are three
pnp_readconf() calls, the first two are with constant strings ("/boot/xxx1",
and "/boot/xxx2" - I cannot remember), and the third, with the parameter:
pnp_readconf( fname ). But in the file, there is:
pnp_readconf( "fname" ).
--------------^-----^
So with it, we cannot use another config file, as the code tested that name:
"fname". (But on the error report, it reports the normal filename - fname.)
>How-To-Repeat:
vi /usr/src/sys/i386/boot/common/pnp.c
108G
>Fix:
substitute "fname" with fname :-)
f"x;x (a'la vi)
