4 Subject: [PATCH 3/3] pseudo_client.c: support multiple directories in
7 For OpenEmbedded it is highly unlikely that using the build host passwd
8 file is the right approach. Most packages can be built with a pseudo
9 that was configured --without-passwd-fallback, since
10 PSEUDO_PASSWD=${STAGING_DIR_TARGET} suffices.
12 This fails when building images, because image.bbclass (correctly)
13 overrides to PSEUDO_PASSWD=${IMAGE_ROOTFS}. However, the rootfs
14 /etc/passwd is not created until the post-install phase of base-passwd,
15 which is long after a passwd file is required. For example, the smart
16 RPM interface wants to look up uid 0 right away. The right solution
17 here is to look first in ${IMAGE_ROOTFS}, then fallback to
18 a location holding immutable files with the minimum user/group settings
19 necessary to successfully get base-passwd onto the target.
21 Rather than rework pseudo to change PSEUDO_PASSWD_FALLBACK to be a
22 run-time rather than compile-time specification, rework the handling of
23 PSEUDO_PASSWD so that it is a colon-separated list of directories that
24 are processed in order.
