Package: initramfs-tools-core
Version: 0.142
Severity: grave
Justification: renders package unusable

Dear Maintainer,

mkinitramfs reports a series of errors of this kind:
/sbin/modprobe not found
depmod not found

I'm attaching a file of the output.

Is this bug related to the usr-merge problem?

Ciao.
Gigi.
