From: Chen Qi <qi.c...@windriver.com> The series of patches add support to read-only rootfs.
The main idea is to use symbolic links to create the illuion that some directories are writable in case of a read-only rootfs. This set of patches have been tested on minimal images with and without 'read-only-rootfs' image feature enabled. Everything is OK. For sato images, everything is the same as before if 'read-only-rootfs' is not enabled. With 'read-only-rootfs' enabled, sato image could work if graphic interface is diabled. When all postinstall problems are resolved, sato image should work well (maybe with some small changes in volatiles-readonly-sato conf file). The following changes since commit 90c0eb29f0b41e4ac2d3d17ebad7295c2ebdc02a: rootfs_rpm.bbclass: remove debug code (2012-12-19 21:43:55 +0000) are available in the git repository at: git://git.pokylinux.org/poky-contrib ChenQi/readonly-rootfs http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=ChenQi/readonly-rootfs Chen Qi (4): sysvinit: add ROOTFS_READ_ONLY variable to rcS-default image.bbclass: add two hook funtions to support read-only rootfs core-image.bbclass: support read-only-rootfs image feature initscripts: support read-only rootfs meta/classes/core-image.bbclass | 7 +- meta/classes/image.bbclass | 29 ++ .../initscripts/initscripts-1.0/bootmisc.sh | 9 +- .../initscripts-1.0/populate-volatile.sh | 281 ++++++++++---------- .../initscripts/initscripts-1.0/volatiles | 1 + .../initscripts-1.0/volatiles-readonly-minimal | 8 + .../initscripts-1.0/volatiles-readonly-sato | 14 + meta/recipes-core/initscripts/initscripts_1.0.bb | 11 +- meta/recipes-core/sysvinit/sysvinit/rcS-default | 4 + meta/recipes-core/sysvinit/sysvinit_2.88dsf.bb | 2 +- 10 files changed, 210 insertions(+), 156 deletions(-) create mode 100644 meta/recipes-core/initscripts/initscripts-1.0/volatiles-readonly-minimal create mode 100644 meta/recipes-core/initscripts/initscripts-1.0/volatiles-readonly-sato -- 1.7.9.5 _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
