</I>>>>><i> I'm not sure why this isn't working but perhaps someone more familiar

</I>>>>><i> I was under the impression the initrd would be regenerated at the end?
</I>>>>><i> Does this even happen or have I just assumed this? I'm pretty sure in
</I>>>>><i> the past it did used to regenerate it but I could be mistaken.
</I>>>>><i>
</I>>>>><i> So the question then remains, how do we ensure that either:
</I>>>>><i> a) the initrd is regenerated at the end of the install process
</I>>>><i>
</I>>>><i> That's ensured at the bootloader installation step.
</I>>>><i> If not present for every configured kernel, an initrd will be created.
</I>>><i>
</I>>><i> What if the initrd is present? e.g. it was created when the kernel was
</I>>><i> installed. Would it still be REgenerated at this stage? (I always
</I>>><i> presumed it would be or that it was not generated at the install time).
</I>>><i>
</I>>><i> Looking at the script /sbin/installkernel I see:
</I>>><i>
</I>>><i> [ -z "$DURING_INSTALL" ] || exit 0
</I>>><i>
</I>>><i> So it shouldn't do anything when run as part of the kernel post
</I>>><i> install... So perhaps some other package triggers an initrd generation?
</I>>><i>
</I>>><i> Looking at things happening live... I see that the symlink
</I>>><i> initrd-desktop.img is created, but it points nowhere. I wonder could one
</I>>><i> of the bootsplash scripts do something like resolve the symlink name and
</I>>><i> then recreate the initrd automatically because the file does not exist?
</I>><i>
</I>><i> The initrd was generated at 12:49:00 So it was after these packages were
</I>><i> installed that it happened....

</I>
As there was a period where the symlink existed but the initrd did not,
I am presuming running /sbin/install kernel exited correctly without
creating the initrd.
However, both plymouth and mageia-theme-Default seem to correctly honour
DURING_INSTALL.
I'm confused as to what is causing it to be generated... can anyone else
see it?
