Hi all,
I'm trying to switch from OE classic to the new openembedded-core.
Using the latest commit on the denzil branch, I've successfully made a
meta layer and built a filesystem that looks reasonably similar to the
old one. But, it seems like something has changed in the boot process.
As the last step in initramfs/init.sh, after mounting the filesystem,
the kernel would attempt to execute /sbin/init like this:
exec switch_root -c /dev/console /mnt/root /sbin/init
With the same old kernel and my new filesystem, this occurs:
switch_root: can't execute '/sbin/init': No such file or directory
When I look at the filesystem, /sbin/init is, of course, nowhere to be found.
Has the boot process changed? What should I be doing instead of
calling /sbin/init?
Cheers,
Brandon

You should check your new rootfs. is there anything called init on it, even in
a different directory? Are you using meta-oe and systemd?
You should have some type of an init in the new filesystem.. if not, then
something is wrong with your image and you'll need to diagnose that first.

So far as I can tell, there is no file named init in the filesystem.

meta-oe: yes
systemd: only if it is enabled by default, so I don't think so. I can
still see /etc/rc[0-5].d, so I think that means Sys V is still in
place.

Sounds like I have something amiss with my filesystem.
Is there a way to tell which package previously generated /sbin/init,
so I can see whether it has changed?

Brandon

meta-oe may have systemd enabled by default, but I'm not sure. I haven't used
it recently enough to know for sure.

Usually busybox, or sysvinit are the packages that generate that binary. You
should be able to see if either was built. Search the filesystem for systemd
may tell you as well..

Just to wrap this up for the sake of future googlers: in my image
recipe, I was doing this:
inherit image
instead of:
inherit core-image
I had also omitted task-core-basic from my IMAGE_INSTALL list. I'm not
certain which solved the problem, but /sbin/init definitely now
exists.
Cheers,
Brandon

Almost certainly the latter rather than the former - inheriting image rather
than core-image is perfectly OK, but without task-core-basic there's a whole
heap of things you won't get including task-core-initscripts which includes
sysvinit.
Sorry you had to go through pain here but glad you solved it in the end :)
Cheers,
Paul
