Hello,
This is follow up of the
patch: https://groups.google.com/g/isar-users/c/MYQDhaHPtX0/m/2ZWf0he8CgAJ
Some recipes use a predefined control.tmpl file instead of generating it
with the debianize class.
Thanks,
Badrikesh

You are missing the most important control point:
meta/classes/debianize.bbclass
But not already the changes here justify a RECIPE-API-CHANGELOG.md entry.
BTW, what about meta-isar/recipes-app/snake4/files/debian/control
and meta-isar/recipes-bsp/optee-examples/files/debian/control.tmpl?

Why making this a variable? optee-client already hard-codes it to no.
Applies to the others as well.

Do we have packages in isar where we know that root is indeed needed?

Thanks for bringing this upstream as well. I hope they will backport the
fakeroot fix, as indicated in 1114644. Once we have that, we can / have
to also update the kas container.
Anyways, your patch does not fix the hang, it just makes it less likely
as now more packages are build without fakeroot. It merely is an
optimization.
While debian does not recommend to set this to yes, I'm wondering if the
default is still yes (or if that changed in trixie).

Hi Jan and Felix,
Thanks for your response.

I saw the patch from Issac True, did the changes in debianize.bbclass: https://groups.google.com/g/isar-users/c/MYQDhaHPtX0
Avoided duplicating here.

Yes, I initially thought the same, but needed some suggestions. Since I didn't find any recipe requiring root permissions to build (as we're not installing anything to the system paths), I also tested building all the recipes with Rules-Requires-Root: no. The build progressed fine.
On salsa.debian.org, I checked some package sources like Linux, U-Boot, etc., and they build without requiring fakeroot.
Should I avoid creating a variable and setting it to no by default for all of these ?

With dpkg version 1.22.13, which is present in Debian Trixie, the default value is no.
In dpkg versions used in Debian Bookworm and earlier, the default value of Rules-Requires-Root was binary-targets.

Yes, that's true. I also noticed that it builds slightly faster on Debian Bookworm-not a significant difference, but it may become noticeable with longer tasks.

Badrikesh
