[systemd-devel] Exploring Minimal Systemd in Initramfs for Faster Boot

Hi Serenissi,

Thanks for your valuable comments.

Yes, egt depends on libraries and examples under /usr/share in rootfs.

yes something similar to this, I will experiment this and get back to you.

and I think since the egt service and its libraries depend on the full 
rootfs, integrating initramfs might not provide significant benefits in 
terms of faster launch time. The time saved by using an initramfs to 
launch basic services earlier would likely be offset by the delay in 
mounting the root filesystem, which is necessary for accessing the egt 
libraries.
