... and remove_kmp_modules
The first call is supposed to check whether the kernel at hand is in an inconsistent state before adding the KMP. But this is a very rare situation; has_unresolved_symbols() is a slow operation (calling depmod) and should thus not be called without good reason. If adding the kmp failed and OPT_DEBUG=1, we carry out this operation to provide a clue to users.
Fall back to full depmod if this fails
This test is bogus because remove_kmp() is called after the actual package removal. The symlinks may still be present, but either point to a different KMP, or be stale.
Rather than reading "_kernel_" from stdin, use a function argument.
With initrd in posttrans and incremental depmod, the logic for depmod and initrd rebuilding will become different.
Like for KMPs, the information whether modules are present in the initrd is also valuable for deciding if the intird must be rebuilt for kernel subpackages. For the time being, we always set the _kernel_ flag, forcing the initrd to be rebuilt for these packages, too.
With this patch, if the $INITRD_IN_POSTTRANS environment variable is set in weak-modules2's environment, it will postpone the rebuilding of the initramfs to the %posttrans stage if possible. Also, for kernel subpackages like -extra or -optional, the initrd rebuild will only be triggered if it's necessary (i.e. if the current initrd contains at least one of the modules in the package).
