clr-init's Issues
Boot doesn't continue
Hi,
I tried to use this via the bundle bootloader-extras. When changing the kernel cmd line to use init=/init (see why here https://community.clearlinux.org/t/bootloader-extras-apparently-not-working/2636 ) then the boot process stops at some point. The system is not hanging, it responds to usb events or ctrl+alt+del but doesn't seem to want to reach the multi-user target or so.
An smaller and simple initrd
instead load systemd and all its stuffs clear could have a custom init process, just doing the needed things to mount root
clr-init pulls /usr/lib64/haswell versions of libraries, won't work on non-AVX2 systems.
The initrd Makefile code relies on ldd which will provide the AVX2 optimized libraries as link targets if it runs on a machine that has AVX2.
This makes the initrd nonfunctional on all non-AVX2 systems, such as IVB.
The code can not rely on ldd plain output for finding required libraries. It should remain functional on older platforms.
