Problems with do_rootfs when changing the user password

Problems with do_rootfs when changing the user password

[S.Jaritz]

[-- Attachment #1: Type: text/plain, Size: 1678 bytes --]

Hej

I want to change the root password. For that I create the recipe 
"myNewPassword.bb" with:
################
SUMMARY = "my new password"
SECTION = "new"
LICENSE = "CLOSED"

inherit extrausers

EXTRA_USERS_PARAMS = "\
        usermod -P xyz root; \
"
################

compiling and packaging works fine.

In my layer I add at the layer.conf:
################
IMAGE_INSTALL_append=" myNewPassword"
################

When do_rootfs (core-image-minimal) the package could not be found. A 
deb(ug) Package was created.

Regards!

Hi,
Its better to change root passwd within ROOTFS_POSTPROCESS_COMMAND

Something like that:

set_root_passwd() {
    .....change passwd here
}

ROOTFS_POSTPROCESS_COMMAND += " set_root_passwd;"

Thanks,
Oleksandr Poznyak!

If your package would contain no files, bitbake will not produce it at all.
You should be able to override this with:
    ALLOW_EMPTY_${PN} = "1"

Hej

Thanks for the infos. I figured out that the common tutorial under 
meta-skeleton does not covers the change of the root password. Although 
"usermod -P" does not exits. Now the "usermod -p" wants a encrypted 
password. Looks like most of the examples at the www are little outdated. 
My question is now:

How are the steps to (re)set the root password?

If you like I would prefer to solve this question like a tutorial.

The starting point is a own layer ("myLayer") and a password 
("myNewPassword1234").

Regards!

[Rudolf J Streif]

Hi,

I am using something like this to set passwords:

inherit extrausers

# set image root password
ROOT_PASSWORD = "secret"
DEV_PASSWORD = "hackme"

EXTRA_USERS_PARAMS = "\
    groupadd developers; \
    useradd -p `openssl passwd ${DEV_PASSWORD}` developer; \
    useradd -g developers developer; \
    usermod -p `openssl passwd ${ROOT_PASSWORD}` root; \
"
\0

Shameless plug here, please excuse: I am explaining this and more in my book "Embedded Linux Systems with the Yocto Project".

> ("myNewPassword1234").
> 

Using your own layer for your custom distro/image configuration is the way to go. Just put the code above into your image recipe like this:

SUMMARY = "Custom image recipe from scratch"
DESCRIPTION = "Directly assign IMAGE_INSTALL and IMAGE_FEATURES for \
               for direct control over image contents."

LICENSE = "MIT"

# We are using the assignment operator (=) below to purposely overwrite
# the default from the core-image class.
IMAGE_INSTALL = "packagegroup-core-boot packagegroup-base-extended \
                 ${CORE_IMAGE_EXTRA_INSTALL}"

inherit core-image
inherit extrausers

# set image root password
ROOT_PASSWORD = "secret"
DEV_PASSWORD = "hackme"

EXTRA_USERS_PARAMS = "\
   groupadd developers; \
   useradd -p `openssl passwd ${DEV_PASSWORD}` developer; \
   useradd -g developers developer; \
   usermod -p `openssl passwd ${ROOT_PASSWORD}` root; \
   "

Best regards,
Rudi

Hej Maxin,

Great Idea - The wiki was my starting point. By the way there is no 
"usermod -P". I can tell only for my self, but I like the meta-skeleton 
section. A working example is better than 10 e-mails. From my Yocto newbee 
view I would prefer some simple lean recipes as templates(or reverse 
engineering). Like:

add user
add group
change root pw
cmake
cmake + change cmake environment var
...

@Rudi: Maybe you whant to add your soultion to the meta-skeleton?
@Maxin: Maybe you make a link into meta-skeleton to Rudis soultion?

Regards!
