The problem , is caused because now , the script make ROOT like this
ROOT/sbin/upgradepkg or other tool from this packages
If the ROOT DESTDIR not have the tool installed (installpkg/upgradepkg) , then fails , cause executable no exists under custom dir destination.
This now breaks totally some particular usages , as a little example , livekit from eric (alienbob) , make separated squashfs container using --root argument , now all fails , cause not all squashfs have the tools installed , this force to install this package in every series , and IN OUR CUSTOM ADDONS , cause we cant do now as example a new nvidia squashed file container cause the command fails if not install pkgtools under same dir , and remove it later to clean squashfs.
Imagine we have nvidia-466.67....txz , and we try to make our addon ,
ROOT=folder-to-make-our-squash installpkg nvidia....txz -----------> fails
installpkg --root=folder-to-make-our-squash nvidia...txz ---> fails
I know , eric provide this addon , okey ..imagine try wahtever you want ... need first install pkgtools , to desired custom root dir , install our package , and later remove pkgtools from the custom dir.
pkgtools-15.0-38 is totally breaked for me.
