read only rootfs & systemd

read only rootfs & systemd

[Maciek Borzecki]

Hi,

Is read-only-rootfs supported on systemd setups?

The current dev manual is not clear about this. Also in image.bbclass
there are comments that read_only_rootfs_hook supports only sysvinit
setups.

Thanks,

Not in oe-core, no. https://github.com/MentorEmbedded/meta-ro-rootfs is how
we're handling it at mentor today, we haven't gotten around to pursuing an
upstream solution, whether integration of this or something else, as of
yet. If you follow the instructions at
https://github.com/MentorEmbedded/meta-ro-rootfs#usage it should work fine
for you.

Christopher,
  Thanks for the information.  I too have been looking for this.

It seems odd to me that this build system that is designed for an embedded
device, doesn't have this feature by default.
