Description Landon Curt Noll 2001-05-06 22:42:16 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.17-14 i686)

Description of problem:
The rc.sysinit attempts to modify the /boot/System.map symlink
each time it is run.  This makes is annoying when one wants
to mount /boot as a read-only file system.

How reproducible:
Always

Steps to Reproduce:
1.build a system where /boot in on a separate file system
2.after the system is brought up and installed, change fstab
  so that /boot is mounted read-only
3.reboot
	

Actual Results:  On startup you see a message about attempting to modify
a read-only file system.

Expected Results:  No errors about attempts to write into /boot.
Since /boot/System.map is already a symlink
to the correct /boot/System.map-XYZZY file,
no attempt to reform the symlink should have
been made.

Additional info:

Try this symlink:

  	ln -s -f System.map-`uname -r` /boot/System.map

  if [ ! -e /boot/System.map -a -r /boot/System.map-`uname -r` ] ; then
