Thanks Bernard

I tried patching the shadow file but couldn't make it work

My requirement is specific ,wanted to modify /etc/shadow file of rootfs

I don't know how /etc/shadow file is getting generated in my rootfs,though
I know the whole
Process of how /etc/passwd file is generated in my roofs .

Inside poky I have a recipe file which will generally fetches the
passwd.master from web and copy it to
/etc/passwd file of my rootfs .

But couldn't find any such process for /etc/shadow file

I have to disable one of the user account and that requires asterisk(*) to
be put in second column of user-specific line.

For example in /etc/shadow have to change

my_user::0:0....

to

my_ user:*:0:0...

+ Khem Raj here as he made most of work of shadow packaging in poky

Thanks
Rajan

I use this snippet to modify my passwd file so I'm sure you could adapt
it for the shadow file.

ROOTFS_POSTPROCESS_COMMAND_append = " \
  sed -i 's/*/x/' \
  ${IMAGE_ROOTFS}/etc/passwd ;"
