I still don't see why a new package is needed.  I suggested linux-base
and you said 'uswsusp doesn't need the kernel package (you can boot from
a floppy)'.  But linux-base doesn't require you to install any kernel
package (and floppies are soooo 20th century).

I don't think this is necessary.  The installer writes a default now and
should continue to do so.  On upgrade, the initramfs-tools or uswsusp
resume configuration (if present) should be copied to this file.  Anyone
who wants to change this can probably deal with a little text file.

It's usual practice now to include '.conf' at the end of configuration
file names.  Also, it might also be worth looking at where other
distributions store this configuration.

This only makes sense if the two implementations of resume provide
compatible command-line interfaces.
