[yocto] Applying Patch to /etc/passwd file in Yocto

[Amit Tomer]

I wanted to apply a patch file /etc/passwd but after many attemps
din't get any success

Below is the file

poky/meta/recipes-core/base-passwd/base-passwd_3.5.26.bb

which is responsible for copying  the modified passwd file to
/etc/passwd in my final image

install -p -m 644
${STAGING_DIR_TARGET}${datadir}/base-passwd/passwd.master
${STAGING_DIR_TARGET}${sysconfdir}/passwd

I believe above line copying the passwd file to /etc/passwd in my final image.

Now I need to modify this passwd furthur, so write a patch for it
belwo is my patch.

Above is my patch

Exact patch of file to be patched is

/tmp/work/k2-poky-linux-gnueabi/image-k2/1.0-r0/rootfs/etc/passwd

Now below error we are getting while applying patch


ERROR: Command Error: exit status: 1  Output:

Perhaps you used the wrong -p or --strip option?
