deb package created by dm.pl is not compatible for dpkg v1.14(from Cydia/Telesphoreo repo)

[r-plus]

What are the steps to reproduce this issue?

1. create deb package by latest(I'm using 827684e) theos with dm.pl
2. install it to jailbroken device that installed dpkg v1.14.
3. all files in deb file are extracted to root directory.

What happens?

All files in deb file are extracted root directory.
This is "Installed files" list on cydia.

What were you expecting to happen?

keep directory structure.

Any logs, error output, etc?

No error log while installing deb package.

Any other comments?

If I switch back to dpkg-deb, this problem is fixed.
So I'm thinking this cause is dm.pl.

What versions of software are you using?

Operating System: …
macOS 10.14.4

Toolchain Version: …
Xcode 10.2

SDK Version: …
9.2

Is the package structure after building it flat?

@uroboro not flat at least checked by dpkg -c command on iOS.

./ prefix is difference to dm.pl version. Is this cause to this issue...?

[kirb]

Is this still happening with up-to-date Theos?

[r-plus]

yes, latest theos (a64c56d) and dm.pl (b4f1d81) still same results with dpkg v1.14.

But in recently jailbroke environment, this doesn't really matter, as they shipped with updated version of dpkg.
