 |
|
The last couple of months there has been a lot of development on sys-kernel/installkernel. That's appreciated, there's a lot of newer functionality, but as someone who uses his own scripts to update and install the kernel, I'm not using a lot of it. That's no problem, most of the things I don't need, like automatic dracut invoking, systemd, grub, uefi or uki functionality, depend on USE flags and are disabled by default. Great!
But now since I think installkernel-44, there's two things that I can't just disable.
I use to install the kernel. I suppresses all normal output and only shows error messages. However installkernel now prints out
| Code: |
* Checking available disk space on /boot...
* Disk space okay. Need at least 22097 KiB, found 365001856 KiB.
* Appending installed kernel to /var/log/installkernel.log...
|
to STDERR instead of STDOUT. Even though these clearly aren't error messages, they print out and mess up the output of my scripts. I could put | Code: | | make -s install 2>/dev/null |
but then I'll miss any actual error messages should they arise. I hope in a future version this is adjusted to STDOUT.
Second annoyance is the new log file /var/log/installkernel.log. Why not just log to syslog? That way logging and rotation are all automatically taken care of. Or make it opt-in. I for one don't see a need for this to be logged. |

File a bug if you want developers to revert the installkernel behaviour, more effective than posting here about it. |

You can locally override anything by either:
- overriding the provided /usr/lib/kernel plugin in /etc/kernel (empty file with the same name effectively disables the plugin), or
- setting KERNEL_INSTALL_PLUGINS, INSTALLKERNEL_POSTINST_PLUGINS, INSTALLKERNEL_PREINST_PLUGINS explicitly to what you do want executed.
These details are documented on the wiki: https://wiki.gentoo.org/wiki/Installkernel

I don't want to add another USE flag for something that has no extra dependencies, besides everything is overridable at runtime anyway. The reason for the logging is twofold:
- it assists with helping users on our support channels, since it allows to backtrack exactly what installkernel has done and how it was configured, and
- it makes it possible to properly fix kexec-tools: https://github.com/gentoo/gentoo/pull/37742 (WIP)

That should not be the case, these hooks use echo like all the other ones. Is this installkernel with the systemd flag enabled or disabled?

Logrotation via logrotate I have fixed in the new version I pushed today.

Ah, I checked the man-page but didn't think to look on the wiki. I'll go through it.

I understand. If it's overridable I have no problem with it anyway, I'll go through the wiki and find out how.

Disabled. In fact there's no USE flags enabled at all. And I'm on installkernel-46 right now.
Thanks for responding AndrewAmmerlaan! Am off to check the wiki. |

It seems there was indeed some strange redirecting to stderr going on. I removed this for info/warn messages: https://github.com/projg2/installkernel-gentoo/commit/f2093f70c18db9fa815c3f1f10aa7d5d987be4a4
Please try again with version 47.
