error updating systemd cgroup-hybrid SOLVED

[mlybarger]

i have an error updating my world, the systemd tells me that it doesn't like this use flag. i don't know that i ever set or used this flag.

how can i resolve this?

Code: Select all

 * USE:        abi_x86_64 acl amd64 bpf cgroup-hybrid curl dns-over-tls elibc_glibc gcrypt kernel-install kernel_linux kmod lz4 openssl pam pcre policykit python_single_target_python3_11 resolvconf seccomp sysv-utils zstd
 * FEATURES:   network-sandbox preserve-libs sandbox userpriv usersandbox
 * This system appears to be booted with the 'hybrid' cgroup layout.
 * This layout obsolete and is disabled in systemd.
 * Disable the 'cgroup-hybrid' USE flag.
 * Rebuild any initramfs images after rebuilding systemd.
 * ERROR: sys-apps/systemd-256.7::gentoo failed (pretend phase):

Code: Select all

 * Disable the 'cgroup-hybrid' USE flag.
 * Rebuild any initramfs images after rebuilding systemd.

I think the message is very clear what to do.

Initramfs images include genkernel, dracut, gentoo-kernel, or gentoo-kernel-bin (as the most common tools) depending on your setup.
If you don't use any of these, then just the USE flag will be enough.

thanks for the reply. it's actually not clear. i didn't even add this use flag or set it. i looked at the options to unset it, but even after using ufed to set so that it has a minus sign on the left, it's gives the same error.

Code: Select all

lightning /home/mark # grep cgroup /etc/portage/make.conf 
lightning /home/mark # 

when i use ufed, it shows >=sys-apps/systemd-249.9 with a plus sign, but nothing is selected on the left. when i cycle through the options (plus adds a plus sign to all 4 items there), a negative or minus sign leaves the >=systemd-249.9 with a plus and everything else has a minus sign.

what initramfs are you using?

What is the output of "grep cgroup /proc/mounts"

[mlybarger]

i have gentoo-sources built with genkernel if that matters. here's the output.

Code: Select all

lightning /home/mark # grep cgroup /proc/mounts

Your initial output shows that USE=cgroup-hybrid is enabled. What is the output of grep -r cgroup-hybrid /etc/portage/package.use?

[mlybarger]

i think you hit the nail on the head. i found this

Code: Select all

lightning /home/mark # grep -r cgroup-hybrid /etc/portage/package.use
/etc/portage/package.use/zz-autounmask:>=sys-apps/systemd-249.9 cgroup-hybrid

and removed it. seems this was pulled in and maybe set by snapd. now my system is updating. thanks! marking as solved.
