Error running on Android (Termux)

I'm getting the folloing error:

$ type qemu-x86_64
qemu-x86_64 is /data/data/com.termux/files/usr/bin/qemu-x86_64

though I do have booth qemu-system and qemu-user installed.

I've tryed setting root_path but that doesn't seem to have any effect:

$ cat ~/.udocker/udocker.conf
[DEFAULT]
root_path = /data/data/com.termux/files/home/.theme.sh/bin:/data/data/com.termux/files/home/.local/bin:/data/data/com.termux/files/home/.kitty-tmux:/data/data/com.termux/files/home/.cargo/bin:/data/data/com.termux/files/home/.krew/bin:/data/data/com.termux/files/usr/bin:/data/data/com.termux/files/home/go/bin

Error: while extracting image layer

Apply this fix for udocker to extract images properly in Android environment -

You should use proot provided by Termux.The one provided by udocker doesn't work properly -

Thanks, I'll give this a try.
Is there a way udocker could detect that it's in Termux and use different paths?

Maybe by checking if ${PREFIX} is set and/or checking ${OSTYPE}, or uname -o

$ echo $OSTYPE
linux-android

$ uname -o
Android
