well... i finished installing gentoo today.
now i found out that i forgot to install a module.
now i want to know how do i reinstall my kernel (meaning, i want to know if just going to /etc/src/linux and doing make mrproper, make config, make dep, make clean... etc. and copying the new bzImage, will screw anything?) |

No, it will not break anything.
It is common to need/want to change a kernel later. As long as you don't remove anything you need, you will not hurt anything. |

If you use LILO as a bootloader, you will need to do /sbin/lilo after the copying. You do not need to do that for GRUB.
EDIT: And make sure to do "mount /boot" before copying! |

Everything should be OK, though you might want to give your new kernel a different name (edit the top-level Makefile and change EXTRAVERSION variable, and don't copy bzImage over your existing one) so that you can easily fall back to the old kernel in case something doesn't work.
If it's a single module you forgot to install, quite often it's possible to just compile the missing module and install it into your existing /lib/modules directory.
