I'm not sure if this has been done already or not (let me know if it
has), but I've just noticed that after playing with several
developmental kernels I had about 30 to 40 different versions of
vmlinuz, initrd.img, config, and System.maps in my /boot directory, not
to mention all the modules loaded in /lib/modules.

So I wrote this perl script that let me pick and choose what I wanted to
clean up.  Be careful, this must be run as root, and although the
default is to do nothing, if you hit a "y" in the wrong place, you can
lose that kernel.

The script is here:

http://www.kihontech.com/code/clean-boot.pl

Here's the usage:

# ./clean-boot.pl -h

usage: clean-boot.pl [-b boot_dir] [-m module_dir]
  (version 0.1)
   default boot_dir = /boot
   default module_dir = /lib/modules

It's run like the following:

---
#./clean-boot.pl
List of versions found:
  2.6.12-1-386              2.6.14                    2.6.14-2-386
  2.6.14-2-k7-smp           2.6.14-kthrt2             2.6.14-rt13
  2.6.14-rt13-logdev1       2.6.14-rt15               2.6.14-rt20
  2.6.15-rc3
Remove files for version 2.6.12-1-386 [y/N/l/q/?]:  ?
  y - remove files from boot and modules
  n [default] - skip this version
  l - list the found versions again
  q - quit
  ? - display this message
Remove files for version 2.6.12-1-386 [y/N/l/q/?]:  q
---

If you hit "y" (or yes or ye, case is ignored), it will then remove any
of the vmlinuz, initrd.img, config and System.map files for version
2.6.12-1-386 in /boot and the directory /lib/modules/2.6.12-1-386.

This is under just a public license, no warranty, so just be careful not
to delete too much.

Also remember to update lilo or grub, since this doesn't handle that.

Comments?
