Bug 879229 – sys-apps/systemd-252 with USE -tpm installs services for pcrphase but not the executable

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description stealth 2022-11-02 23:17:47 UTC]

the following services are installed and enabled by default:
systemd-pcrphase-initrd.service
systemd-pcrphase-sysinit.service
systemd-pcrphase.service

they rely on systemd-pcrphase executable which is understandably not installed because its related to tpm.

I have USE="tpm" set, but had to mask the services as a quick fix for my laptop to be able to bootup with measured boot. systemd-pcrphase-initrd.service at least doesn't have a timeout making my laptop wait indefinitely.

(I have merged /usr and enabled the merged-usr profile so not sure if the paths below should be just /lib or /usr/lib)

I copied the 252 ebuild to my local repo and added:

if ! use tpm; then
    # mask systemd-pcrphase services which depend on tpm
    dosym /dev/null /usr/lib/systemd/system/systemd-pcrphase.service
    dosym /dev/null /usr/lib/systemd/system/systemd-pcrphase-initrd.service
    dosym /dev/null /usr/lib/systemd/system/systemd-pcrphase-sysinit.service
fi

below the if use split-usr conditional in multilib_src_install_all function

systemd is no longer in degraded state after that

These are the symlinks I have after using "systemctl mask ...":

It looks like recent systemd releases do not install those unit files when USE="-tpm". Please re-open if this is still an issue.
