Subject: dpkg: don't spawn a subprocess when it's not needed

Date: Fri, 25 Oct 2024 00:41:56 +0200

[Message part 1 (text/plain, inline)]

Package: dpkg
Version: 1.21.22
Severity: wishlist

Dear Maintainer,

I'm working on the dpkg codebase, and I've found that when extracting a
.deb with an uncompressed data.tar, we can install it even without calling
dpk-deb as subprocess.
Find a patch attached.

Regards,

-- Package-specific info:
This system uses merged-usr-via-aliased-dirs, going behind dpkg's
back, breaking its core assumptions. This can cause silent file
overwrites and disappearances, and its general tools misbehavior.
See <https://wiki.debian.org/Teams/Dpkg/FAQ#broken-usrmerge>.
