Failed to build read-only-rootfs image for imx6qsabreauto

[csoapy]

I bitbake core-image-minimal successfully by following steps in README.

But after adding this line to local.conf

EXTRA_IMAGE_FEATURES += "read-only-rootfs"

 and bitbake again, I got error:

ERROR: core-image-minimal-1.0-r0 do_rootfs: The following packages could not be configured offline and rootfs is read-only: ['100-initscripts']
ERROR: core-image-minimal-1.0-r0 do_rootfs: Function failed: do_rootfs
ERROR: Logfile of failure stored in: .../fsl-release-bsp/build-fb/tmp/work/imx6qsabreauto-poky-linux-gnueabi/core-image-minimal/1.0-r0/temp/log.do_rootfs.21691
ERROR: Task 9 (.../fsl-release-bsp/sources/poky/meta/recipes-core/images/core-image-minimal.bb, do_rootfs) failed with exit code '1'

Saying "100-initscripts" package cause the error, but after checking package list by

bitbake -g core-image-minimal && cat pn-depends.dot | grep -v -e '-native' | grep -v digraph | grep -v -e '-image' | awk '{print $1}' | sort | uniq

there is only initscripts shown, not the "100-initscripts"

So, why there is "100-" before package name?

I find some writing commands in initscripts_1.0.bb, maybe that's the cause of do_rootfs error, but why? Are there some steps I missed?

And BTW, how to set "ROOTFS_READ_ONLY=yes" in /etc/default/rcS before bitbake?

Thx!

Experienced the same issue on my build (using krogoth).
inside meta-fsl-bsp-release, there's a initscripts_%.bbappend thats breaking things. 

Its has a pkg_postinst scritp trying to create a symlink under /etc/systemd/... but on non-systemd based images, this fails as the dir doesn't exist. This failure flags the initscripts recipe's pkg_postinst script for execution upon first boot, which is not allowed for read-only.

I fixed this with my own bbappend: 

pkg_postinst_${PN}_append_mx6 () {

   if ${@bb.utils.contains('DISTRO_FEATURES','systemd','true','false',d)}; then

      ln -s /lib/systemd/system/gpuload.service /etc/systemd/system/multi-user.target.wants/

   fi

}

the if statement blocks the failing line from executing on non-systemd based images.

can you attach the log file here? (log.do_rootfs.21691)

I tried on my BSP build. I didn't meet this error.

my steps:

1.install the fsl-yocto 4.1.15 BSP

2. build the core-image-minimal  (I want to make sure the default setup build is ok)

3. add EXTRA_IMAGE_FEATURES += "read-only-rootfs" in local.conf

4. build the core-image-minimal again.

jimmychan‌,

I have tested this as following:

1. Ubuntu 16.04.4 in VirtualBox 5.2.12 on last Windows 10
2. Ubuntu 14.04.5 in VirtualBox 5.2.12 on last Windows 10
3. Ubuntu 16.04.5 in VirtualBox 5.2.12 on last Windows 7
4. KDE Neon User Edition(based on Ubuntu 16.04) in VirtualBox 5.2.12 on last Windows 7

But the error still exists.

So what's your test environment?
