[PATCH v2 0/1] builddeb: introduce profile excluding the dbg pkg

[PATCH v2 0/1] builddeb: introduce profile excluding the dbg pkg

[Bastian Germann]

Introduce a Debian build profile to exclude the massive debug package
during build. This was sent the first time as part of a patch series:
<20210411101422.7092-6-bage@linutronix.de>

Most of the patch series is included in the current work on mkdebian
but this is still missing.

Changelog:
v2:
 * Align the profile name with the one that ended up in Debian.

[PATCH v2 1/1] builddeb: introduce profile excluding the dbg pkg

[Bastian Germann]

Enabling CONFIG_DEBUG_INFO implies building the binary linux-image-*-dbg.
As this increases package build time significantly, one might want to
exclude it from being built.

Add build profile pkg.$sourcename.nokerneldbg for that package
so it can be excluded via e.g.
`make DPKG_FLAGS="-P=pkg.linux-upstream.nokerneldbg" deb-pkg`

The name is the same that is used in Debian's linux package since version
5.17~rc4-1~exp1.

Did you confirm if this patch saved the build time in any way?
If so, please provide me with the steps to test it.

The correct command is:

 `make DPKG_FLAGS="-Ppkg.linux-upstream.nokerneldbg" deb-pkg`


-P<profile>                         (without '=' for the short option)
       or
--build-profiles=<profile>    (with '=' for the long option)



I will postpone this because just adding Build-Profiles does nothing.
