Add read-only rootfs support to sysvinit startup system.
The main changes are:
1) Let rootfs_xxx.bbclass support 'read-only-rootfs' image feature.
If IMAGE_FEATURES contains 'read-only-rootfs', then the populate-volatile.sh
script is run at rootfs time to set up basic directories and files.
2) Improve the populate-volatile.sh init script.
3) Add two config files specific to read-only-rootfs image, which are to be used
by the populate-volatile.sh script.
4) Automatically adjust the mount options in fstab when 'read-only-rootfs' is in
IMAGE_FEATURES.
Version 2 fixes a problem version one has, that is, if we build an image without
'read-only-rootfs' image feature after we built one that has this feature, the
mount options in fstab is wrong.
initscripts recipe still have that issue.
Cheers,
Yes, you're right.
If we build an image without 'read-only-rootfs' image feature after we
built one that has, all symbolic links used for an read-only-rootfs
image should be removed and corresponding directories should be created.
Thanks a lot for your review and reply. I'll fix this problem and send
out a V3.
Best Regards,
Chen Qi
