Hello,
I have made a multiboot USB using SYSLINUX. For distributions that use
dracut, I can specify the rd.live.dir boot parameter to change the
directory that it looks for filesystem.squashfs in. There are similar
options for other live systems, like Arch Linux's archisobasedir.
This is useful to me because I can put each distribution's filesystem in
its own folder.
I was not able to find such a parameter for Debian, which limits me to
only one Debian-based distribution on the drive because the filesystem
squashfs must be in /boot, and there can only be one.
If a simple livedir= option could be added to specify the directory, it
would help me tremendously.
Thanks,

One way is to stuff your squashfs into an ISO image (nothing else needed
in there, just the subdirectory /live containing your squashfs), and use
one of the iso parameters.
Using the live-media*-Parameters should make it possible to use a
squashfs file directly, without having to wrap it into an iso. I haven't
tried this myself lately, though.

Yeah, I read the manpage right before making this bug.

I didn't think of using the ISO parameters that way, smart idea.
If my idea of having just SquashFSes in their own folders doesn't work,
I'll try this out.

From how I understood the explanation of live-media/bootfrom, it looks
like it wants you to specify a device to look inside /live of. I would
need to create a separate partition for every squashfs, /live in each.
I don't believe there are currently any options that allow me to achieve
my goal without wrapping the squashfs. Thank you for your help!

Like I said, I haven't tried this myself lately, but live-media-path
allows you to change exactly the "/live" part, according to the manpage.
So you could have something like
live-media-path=/mycoolsquashfsgoeshere/ for your custom squashfs and
live-media-path=/officialdebiansquashfsgoeshere/ for an official image,
for example.
You will probably have to combine that with live-media=removable-usb so
it will scan removable USB media only.
I don't see why you would need a different partition for each image, you
should be able to use different live-media-path entries instead (one per
boot menu entry).
