I am supposing that mountpoint is an standard command that comes with
Debian standard packages and thus you don't have to edit any
build-depends variable on the package definition.
it would be a depends, not a build-depends. the initrd is build on the
target system, not on the build system.
/bin/mountpoint is part of initscripts from sysvinit. i'm afraid we
cannot use this - a depends on initscripts is too invasive for systems
running alternative init systems (systemd, upstart, etc).
This is the alternate patch then.
