Comment # 31 on bug 874621 from Michal Marek

I think we should rather check for /lib/modules/$KERNEL_VERSION (i.e. if the
kernel has module support); missing modules.dep is actually a reason to call
depmod. There is also no need to delete the old file, depmod will simply
overwrite this and other files. Also, either print a warning if the depmod
binary is missing, or call it unconditionally and let the shell report it.

type -P is a bash extension, but this check can go away. The rest looks fine.
