[Buildroot] Question on users and ssh access

[Eugen.Hristev at microchip.com]

Hello everyone,

Maybe you can help me with a small matter related to user accounts in 
Buildroot ?

By default the /home directory does not exist, thus when using adduser 
to create a user, the creation of /home/foo fails ... and this causes 
login with ssh to the user impossible due to lack of home dir.

Any recommendation on how to solve this ? It is preferred to set a 
password for root for ssh access (as root has /root as home) ? or add a 
post-script to create the /home in the rootfs ?

Thanks !
Eugen

Thanks, but I do not wish to have new default users for the buildroot 
image (at compile time).

I wish the user who flashes the buildroot image can create new users on 
demand, without the problem that adduser fails in creating their home 
directory

 You can use BR2_ROOTFS_DEVICE_TABLE ("Path to permission tables") to point to a
file that instructs buildroot to create the /home directory.

 Alternatively, you can create an overlay (BR2_ROOTFS_OVERLAY) that contains /home.

 Finally, you can specify the home directory location in adduser's arguments,
for example pointing to /tmp/<user>.

 Arnout
