Did you try "du -hsx /"?

Let me see (I have many old kernel binaries in /boot and /lib and / does
not include /usr /var /home /tmp)
root@goofy:/# df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 1.9G 155M 1.6G 9% /
root@goofy:/# du -hsx /
123M /
It is true that "du" underestimates file usage and / may better have
~200MB or more. Even after removing all old kernels and initrd images,
root@goofy:root# df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 1.9G 79M 1.7G 5% /
root@goofy:root# du -hsx /
46M /
System requires almost 80MB on harddisk. Size of modules in "du"
already exceeds 20MB, so one has no chance having 2 of 2.4 kernels on a
machine with 100MB root partition :) Looking at this, 150MB-250MB seems
the good root partition size these days.
