[RESOLVED] emerge REQUIRED_USE flag constraints

[anvarro10]

I'm attempting to update the system I'm building (Gentoo with systemd on QEMU KVM)

I've been following the handbook and gentoo website's systemd article.
https://wiki.gentoo.org/wiki/Systemd

When I try to emerge --ask --verbose --update --deep --newuse @world OR emerge -avDN @world

Code: Select all

Autounmask changes successfully written.

 * IMPORTANT: 8 config files in '/etc/portage' need updating.
 * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
 * sections of the emerge man page to learn how to update config files.

!!! The ebuild selected to satisfy ">=sys-fs/cryptsetup-2.0.1:0=" has unmet requirements.

  The following REQUIRED_USE flag constraints are unsatisfied:
    exactly-one-of ( gcrypt kernel nettle openssl ) static? ( !gcrypt !udev !fips ) fips? ( !kernel !nettle )

  The above constraints are a subset of the following complete expression:

Not sure if I'm missing or need current USE Flags in make.conf or if I need to remove anything to get systemd going.
Can't tell if the message is telling something I should know?

  The following REQUIRED_USE flag constraints are unsatisfied:

Not sure if I'm missing or need current USE Flags in make.conf or if I need to remove anything to get systemd going.
Can't tell if the message is telling something I should know?

Yes, it is telling you too many USE, which are incompatible with each other, are set on this package.

First off, " exactly-one-of ( gcrypt kernel nettle openssl )" should be pretty straight forward. Enable exactly one, not zero not many.
At the same time, "static? ( !gcrypt !udev !fips )" when static is enabled, it cannot have gcrypt, udev or fips enabled.
Finally, "fips? ( !kernel !nettle )" when fips is enabled, neither kernel or nettle can be enabled.

So you have choices to make based upon that.

The default is to have only gcrypt enabled in the first group, but then static would have to be disabled.

This sort of feels like a case of filling up make.conf with USE flags when there is little understanding why they are there.
I would start minimizing make.conf's USE if that is true.

[Hu]

I agree with grknight's advice.

I will add that USE=static is only needed in certain special cases. Setting it system-wide is almost never the correct answer, but your emerge --info shows it is set system-wide.

If you still need help, post the contents of /etc/portage/make.conf so that we can distinguish which flags you set versus which ones you inherited from your profile.

Tells you that some files REALLY needs to be updated/have changes confirmed.

Thank you grknight and Hu,

Yeah, It's 3rd attempt at installing Gentoo with the intention of running Kubernetes on it.
However, I just can't seem to properly wrap my head around USE.
I'm sure once to you've helped me understand than I can start understanding them.
All I did was blindly add everything handbook/systemd documentation recommended but now I'm thinking that I don't need all these flags system wise to achieve my goal of getting a simple bootable gentoo with systemd as the init system for me to attempt at installing Kubernetes via Kubeadm and Containerd

[Hu]

In the cited systemd wiki page, none of the occurrences of static are to direct you to add it as a USE flag. There is no mention of nettle at all. I suggest you remove from make.conf every USE flag that you cannot explain why you need it. Yes, this may mean removing all the flags, leaving you with just USE="". That is fine. Your profile should provide good defaults, so as long as you do not actively disable flags it enabled, you are likely to have a decent system.

[anvarro10]

Thank you for your advice, That helped me get systemd running and I ended up removing all the USE envs from the make.conf and carried on from there to install the boot loader
