[gentoo-user] /System.map???

[Michael W. Holdeman]

Boot message says can't find /System.map, probably because System.map is 
in /boot. What is this about? Anyone else?

Copy your System.map to /.

If you have separate /boot and /usr partitions, the System.map file is
searched in /.


[quote from /sbin/modules-update]

	for cfg in /lib/modules/${KV}/build /usr/src/linux-${KV} \
	           /boot /usr/src/linux ""
	do
		cfg="${cfg}/System.map"
		[[ -f ${cfg} ]] && break
	done

Yes.

With older baselayout [1], the System.map file wasn't required :
[code]
	if [ -f /usr/src/linux/System.map ]; then
                depmod -a -F /usr/src/linux/System.map ${KV}
        else
                depmod -a ${KV}
        fi
[/code]

One day, the code evolved to :
[code]
	if [ -f /usr/src/linux/System.map ]; then
                depmod -a -F /usr/src/linux/System.map ${KV}
        else
                ewarn "System.map not found - unable to check symbols"
        fi
[/code]

So, developpers decided to search the System.map file in different
paths, but if your /boot and /usr directories are mounted on partitions,
you must copy the file in /, because modules-update is ran before
mounting partitions.

I've made it:

  for cfg in /lib/modules/${KV} /lib/modules/${KV}/build... 


Then you just copy "System.map" to "/lib/modules/${KV}" which is -of course- 
mounted on boot. C'mon Devs!! It's not that hard!!

This could be done during the make modules_install step.

Open a bug :-)

I had been having this too.  I was curious why it started that.  Of
course, I had not rebooted in about two months either.  What affect does
this have anyway??
