It can be parsed like I suggested, but not reliably. Still, this would be better than nothing.

This is arguably the correct solution; in the case of Yes, but users can legitimately use the install directive themselves. > nfs-kernel-server, for example, the 'install' command wants to invoke > sysctl --pattern, but the busybox sysctl installed in the initramfs by > default doesn't support --pattern.

This may be the correct workaround for the modprobe issue, but nfs-kernel-server should still have an hook to add /sbin/sysctl to the initramfs. > 3.

I still suspect that the udev rule would be more elegant than the modprobe.d install directive, but this would still not solve the case of users using the install directive. So maybe initramfs-tools should still be changed to use modinfo. -- ciao, Marco
