[systemd-devel] Q: Reducing systemd Userspace Boot Time Below 2 Seconds on Minimal Embedded ARM Board

2025-07-17 Thread Dharma.B
Hello systemd developers, I'm working on minimizing user space boot time with systemd on an embedded board and would appreciate any advice or insights from the community. Setup details: * Hardware: sam9x75-curiosity-sd (ARMv5), booting from SD card * Distro: Yocto/Poky, custom minimal image

Hi Serenissi, Thanks for your valuable comments. > which means you won't be able to run egt in initfamfs until main rootfs > is mounted anyways? Yes, egt depends on libraries and examples under /usr/share in rootfs. > In theory you can use RootImage to point to /sysroot and start egt after >

2024-09-23 Thread Dharma.B
Hi Team, I'm exploring the possibility of splitting the systemd binary to optimize boot time before and after switching to the root filesystem. I’m aware that the systemd binary is quite large and may not fit in the initramfs, but is it feasible to have a minimal version of systemd that can in

Hi Everyone, We have recently migrated from sysvinit to systemd on our platforms, including sam9, sama5, and sama7 which feature various ARM architectures such as ARMv5, Cortex-A5, and Cortex-A7. We observed different performance levels across these architectures, detailed as follows: Performanc
