[autofs] debugging the automounter

[Philip Ong Jr.]

Are there any good links on how to go about setting up debugging the 
automounter using the gdb?

I’m running rhel3 and trying to figure out an automounter problem. I’ve 
installed the debuginfo package so the binary won’t be stripped.

Does the debuginfo package install another binary to debug the 
automounter using gdb because the binary looks stripped to me…?

# file /usr/sbin/automount
/usr/sbin/automount: ELF 32-bit LSB shared object, Intel 80386, version 
1 (SYSV), stripped

This is NOT stripped…but I’m not sure what this is used for or how to 
use it…
# file /usr/lib/debug/usr/sbin/automount.debug
/usr/lib/debug/usr/sbin/automount.debug: ELF 32-bit LSB shared object, 
Intel 80386, version 1 (SYSV), not stripped

Basically, I’d like to get to the point where I can have an non-stripped 
automounter and how to verify it is not stripped or how to build and 
debug it.

I’d appreciate any help.

Thanks
