Hello Yocto community developers,

 

I am currently working on the task of porting an exis= ting build system to Yocto to create customized Linux distribution for an e= mbedded product. I have successfully created a bare box image, the kernel and root file system image and the system start= up is working fine.

 

I am now investigating on creating the initramfs usin= g Yocto and have gone through the Yocto documents for the same.<= /span>

 

Adding the options :

INITRAMFS_FSTYPES =3D "cpio.gz"<= /span>

INITRAMFS_IMAGE =3D "custom-initramfs" = ; =E0 my = recipe which inherited core-image.bb recipe

 

Results in the creation of ‘custom-image-201701= 20105621.rootfs.cpio.gz’ file.

 

We are using initramfs to run a script which before m= ounting the root file system checks for ima policy and also responsible for= loading the evm-keys. In short, the initramfs contains a script which is executed before mounting the main root file sys= tem. So I think I need to follow a different procedure than the one I menti= oned above for my use case. Also we are using systemd as the init system an= d for the initramfs I don’t need sysv or systemd as all I will do is running a script in initramfs.

 

Is there a better way of creating this structure in Y= octo, any information would be helpful.

 

 

Mit freundlichen Gr=FC=DFen /= Best regards
