[Buildroot] Creating user accounts in rootfs

[Julien Boibessot]

Hi,

Does someone know a better way than the following to create user
accounts ? :
* on the target use "adduser xxx"
* then copy target's "/etc/passwd" and "/etc/shadow" to Host's
"buildroot/target/..../rootfs/target_skeleton/..."
* rebuild rootfs

My goal is to have a rootfs with preset user accounts, ready to be used
as soon as the rootfs image has been flashed.

Thanks
Julien

No, that's certainly the easiest solution (and how I normally do it).

i use an different way (but not with buildroot):

i have 2 functions:

add_user() {
   # Usage: add_user "username" "password" "userid" "groupid"  
"description" "home" "shell"
   mkdir -p ${INSTALL}/etc
   touch ${INSTALL}/etc/passwd
   if [ -z "`grep "$1:" ${INSTALL}/etc/passwd`" ]; then
     echo "$1:$2:$3:$4:$5:$6:$7" >> ${INSTALL}/etc/passwd
   fi
}

add_group() {
   # Usage: add_group "groupname" "groupid"
   mkdir -p ${INSTALL}/etc
   touch ${INSTALL}/etc/group
   if [ -z "`grep "$1:" ${INSTALL}/etc/group`" ]; then
     echo "$1:x:$2:" >> ${INSTALL}/etc/group
   fi
}

that can be called from the buildsripts (like your makefiles) with for  
example:

add_user haldaemon x 68 68 "HAL daemon" "/" "/bin/sh"
add_group haldaemon 68

for the password i dont use /etc/shadow (but you can do this also).
i install an second busybox for my host in in my toolchain dir with  
only CONFIG_CRYPTPW=y is set so i have busyboxs cryptpw utility on my  
host

  i have set an variable ROOT_PASSWORD with my rootpassword

and to set my root password i call the function add_user like:

ROOT_PWD="`$ROOT/$TOOLCHAIN/bin/cryptpw $ROOT_PASSWORD`"
add_user root "$ROOT_PWD" 0 0 "Root User" "/storage" "/bin/sh"
add_group root 0
