image.bbclass: don't let do_rootfs depend on BUILDNAME

2016-01-30T12:01:45+00:00

BUILDNAME is set by cooker as a string of current time. Letting do_rootfs
task depend on this variable gets us no benefit. Besides, letting do_rootfs
task depend on this variable will cause us trouble when executing
`bitbake -S none core-image-minimal'. With current code, this command
gives us error complaining about the different bashhash of do_rootfs task.

image.bbclass: avoid boot error on read-only systemd image

2015-01-15T16:01:33+00:00

New version of systemd implements a new feature of updating /etc
or /var when needed at boot. For details, please see link below.

Opointer.de/blog/projects/stateless.html

For now, at boot time, the systemd-sysusers.service would update user
database files (/etc/passwd, /etc/group, etc.) according to the configuration
files under /usr/lib/sysusers.d. This step is necessary for other systemd
services to work correctly. Examples of such services are systemd-resolved
and systemd-tmpfiles-setup.

The problem is that on a read-only file system, that is, if /etc is read-only,
the user database files could not be updated, causing failures of services.

This patch fixes this problem by adding users/groups at rootfs time.

image: Avoid race over directory creation

2015-01-06T14:13:05+00:00

There is a race over the do_package_qa task and the do_rootfs task
since rootfs recreates a directory. This patch disables the task
(which isn't used for images) to avoid the race:

image.bbclass: search both rootfs and native staging for passwd files

2014-12-31T10:17:29+00:00

When pseudo is configured to disallow fallback to the build host
/etc/hosts and /etc/group, the selection of ${IMAGE_ROOT} for
PSEUDO_PASSWD is insufficient as the necessary files will not be
available until base-passwd has been installed and its pkg_postinst
script run.  Fall back to the ${STAGING_DIR_NATIVE} version of those
files until the rootfs versions are available.  (The native copies are
never modified by the build; the ones in ${STAGING_DIR_TARGET} are
updated and may contain settings not consistent with what would be
created by post-install useradd/groupadd commands invoked in the image
rootfs.

image.bbclass: image_types.bbclass is a must

2014-08-15T17:19:54+00:00

The image_types.bbclass is a must since we use this in image.bbclass:

[snip]
python () {
    deps = " " + imagetypes_getdepends(d)
    d.appendVarFlag('do_rootfs', 'depends', deps)
[snip]

The imagetypes_getdepends() is defined in image_types.bbclass. Use "+="
to replace "?=" since it is a must, so that the user can use
"IMAGE_CLASSES = foo.bbclass" in local.conf to add their own image
class.

NOTE: the IMAGE_CLASSES_append = " foo" doesn't work since we use this
in image.bbclass:
 IMAGE_CLASSES += "image_types"
 inherit ${IMAGE_CLASSES}

I think that it is because inherit takes effect before append?

Another way to fix the problem is:
IMAGE_CLASSES ?= ""
inherit image_types ${IMAGE_CLASSES}

But it seems that we need another name for IMAGE_CLASSES, for example
IMAGE_CLASSES_EXTRA, and also need update the doc, which would make it
complicated.

image.bbclass/rootfs.py: add variables to rootfs[vardeps]

2014-07-23T20:44:19+00:00

Added base variables and package backend specific variables to
rootfs[vardeps] in order for rootfs to rebuild when changes are made.

Set some variables as [func] to inform bitbake that they are shell
scripts, so that it invokes its shell dependency parsing. Without
marking them as functions, changes in the actual function body would
not trigger rootfs rebuilds.
