Bug 487430 – sys-apps/portage-2.2.1 incompletely handles 'kernel-patch' USE flag

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Sergey S. Starikoff 2013-10-09 12:56:01 UTC]

I use sys-fs/aufs3 with kernel-patch USE enabled together with sys-kernel/gentoo-sources (-build -deblob -symlink) kernel (up to 3.10.7-r1) for portage tree.
Extending single kernel compatibility (see bug #438784)
Each kernel update requires much attention and manual actions.

Reproducible: Always

Steps to Reproduce:
Now I must do following:
Actual Results:  
1. Install new kernel.
2. Fix /usr/src/linux symlink (I still prefer to do it manually)
3. Configure new kernel (at least copy existing config and run make oldconfig).
4. make modules_prepare
5. Only here I can patch kernel source tree with aufs3 patch (emerge -1 aufs3), on build without it kernel aufs module fails.
6. Now, I can build kernel and boot with it.

Expected Results:  
In my case (-build -symlink) I expect portage to make a check on installed packages with kernel-patch USE enabled, if present — echo remind from list above.
Maybe, it will be better to patch kernel sources basing not on standard build path (/usr/src/linux), but on kernel install path (for 3.10.7-r1 — /usr/src/linux-3.10.7-gentoo-r1/).

If 'symlink' USE for kernel package enabled — portage should after correcting buildpath symlink automatically rebuild package(s) with kernel-patch USE enabled.

If 'build' USE enabled, portage should prior to kernel build patch its sources (rebuild packages with kernel-patch USE enabled).

PLease use aufs-sources. Those are aufs3 + gentoo-sources.

Thank you!
It is a solution for particular issue of aufs3-support patch.

But in this bug report it's used as example (and currently the only patch, applayed by title USE flag).
If 'kernel-patch' USE flag exist, how it should be handled in ideal.

[Comment 3 Justin Lecher (RETIRED) 2013-10-14 14:15:27 UTC]

Here is nothing more that I can do.

To use sys-fs/aufs3, you will always need

1. fresh kernel sources
2. /usr/src/linux needs to point there (as for all other module ebuilds)
3. rebuild the kernel after the aufs3 patches were applied.

everything else is outside my maintainership.

@kernel, do you like to add something?

How are you going to translate step 3 from your actual to your expected results?

Without a proper .config present, I think this whole idea doesn't really work...

This step will always be outside the portage space.

Okay, then we will close this bug. Current aufs-sources support vanilla+aufs3 and gentoo-sources+aufs3. Everything else will need to have some user intervention.
