RE: [PATCH] debianize: set Rules-Requires-Root in debian/control

["'Prusty, Badrikesh' via isar-users" <isar-users@googlegroups.com>]

Hi,

Thank you for the patch. I was about to send it.

We are facing intermittent freezes with build configuration:
----------------------------------------------------------------------------------
Host system: Debian Trixie
Container image for build: kas-isar 4.8.1 (Debian Bookworm based)
Target Build Distro: Debian-bookworm
----------------------------------------------------------------------------------

Intermittent freezes observed during "do_dpkg_build" task when it runs the cmd: dpkg-buildpackage ----

Debian also recommends doing non-root builds when the build process doesn't installs to system paths (e.g., /etc, /usr). That's why most packages in Debian including linux-image, firmware-nonfree use "Rules-Requires-Root: no".

May be you can update kernel and kernel module recipe files as well and it uses control.tmpl files, and observed freezes with kernel builds.
isar/meta/recipes-kernel/linux/files/debian/control.tmpl
isar/meta/recipes-kernel/linux-module/files/debian/control.tmpl
by settings this: Rules-Requires-Root: no, I successfully built it (no intermittent freezes).

Thanks,
Badrikesh

Subject: [PATCH] debianize: set Rules-Requires-Root in debian/control

Setting "Rules-Requires-Root: no" in the debian/control file avoids unnecessarily calling fakeroot in the build environment. Packages which require root can override the new "DEBIAN_RULES_REQUIRES_ROOT" variable with the desired value.

This is particularly useful when using dpkg-raw, as it no longer needs fakeroot to create the packages. This provides a considerable speedup in some environments (e.g. systems with very high open file descriptor limits and specific versions of fakeroot).
