vmlinuz vs bzImage - Slackware

vmlinuz - Nothing but bzImage file.
config - Config file used for kernel compliation
system.map - Used by kernel ,if it needs to recover from fatal errors.
initrd - Used to mount real root file system


initrd.img is completely different from System.map.

While System.map is used for debugging.
initrd.img stands for initial ram disk,provides initial temporary file system which
allows kernel to mount the real root file system,while booting.

If you have real file system (ext3) build inside your kernel ,rather than using it as an
loadable module,you won't need initrd.
