Bug#588452: "softdep" modules not included in initramfs when MODULES=dep is specified

[Stephen Powell <zlinuxman@wowway.com>]

Package: initramfs-tools
Version: 0.97

"softdep" modules are not included in the initial RAM file system
when MODULES=dep is specified.  Here's an example from the s390
architecture:

/etc/modprobe.d/dasd.conf:

   options dasd_mod dasd=0.0.0200(diag),0.0.0201,0.0.0202-0.0.0203(diag)
   softdep dasd_eckd_mod pre: dasd_diag_mod
   softdep dasd_fba_mod pre: dasd_diag_mod

(/etc/modprobe.conf does *not* exist)

/etc/initramfs-tools/conf.d/driver-policy:

   MODULES=dep

/etc/initramfs-tools/modules:

   (dasd_diag_mod is *not* listed)

dasd_eckd_mod is included in the initial RAM file system.  I assume that
that is due to matching on the alias "ccw:t3990m*dt3390dm*".  dasd_mod
is also included in the initial RAM file system.  I presume that that
is due to the fact that dasd_mod is a hard dependency of dasd_eckd_mod.
But dasd_diag_mod is *not* included in the initial RAM file system,
even though it is listed as a soft dependency of dasd_eckd_mod, which
has already been selected for inclusion.

On the system above, this prevents the system from booting, as the
devices marked for use with the diag driver, including the root file
system in this case, cannot be brought online.  Therefore, the permanent
root file system cannot be mounted.

I am able to circumvent the problem by explicitly listing dasd_diag_mod
in /etc/initramfs-tools/modules, but this should not be necessary.
