base-passwd/useradd: Various improvements to useradd with RSS
Currently there are multiple issues with useradd: * If base-passwd rebuilds, it wipes out recipe specific user/group additions to sysroots and causes errors * If recipe A adds a user and recipe B depends on A, it can't see any of the users/groups A adds. This patch changes base-passwd so it always works as a postinst script within the sysroot and copies in the master files, then runs any postinst-useradd-* scripts afterwards to add additional user/groups. The postinst-useradd-* scripts are tweaked so that if /etc/passwd doesn't exist they just exit, knowning they'll be executed later. We also add a dummy entry to the dummy passwd file from pseudo so we can avoid this too. There is a problem where if recipe A adds a user and recipe B depends on A but doesn't care about users, it may not have a dependency on the useradd/groupadd tools which would therefore not be available in B's sysroot. We therefore also tweak postinst-useradd-* scripts so that if the tools aren't present we simply don't add users. If you need the users, you add a dependency on the tools in the recipe and they'll be added. We add postinst-* to SSTATE_SCAN_FILES since almost any postinst script of this kind is going to need relocation help. We also ensure that the postinst-useradd script is written into the sstate object as the current script was only being added in a recipe local way. Thanks to Peter Kjellerstedt <pkj@axis.com> and Patrick Ohly for some pieces of this patch. [Yocto #11124] Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
