[yocto] Some trivial question about git update-ref refs/heads/rocko ...

This did the trick... Thank you!

I always thought that I actually initially fetched master release, but it
appears that I fetched rocko as genesis release.

The conclusion/fact given above sustains, because of the following info in
the: .../.git/refs/heads/ (CLI transcript follows):

[user at localhost poky]$ pwd
/home/user/YOCTO/oe_core_embedded/poky
[user at localhost poky]$* cd .git/refs/heads*
[user at localhost heads]$ ls -al
total 16
drwxrwxr-x. 2 user user 4096 Dec 21 06:10 .
drwxrwxr-x. 5 user user 4096 Oct 18 12:49 ..
-rw-rw-r--. 1 user user   41 *Dec 21 06:10 master*
-rw-rw-r--. 1 user user   41 *Oct 18 12:49 rocko*
[user at localhost heads]$ cat rocko
65d23bd7986615fdfb0f1717b615534a2a14ab80
[user at localhost heads]$ cat master
*370483fce1c2429c81b19dcf8a36394dc3fc3d92 <<===== MASTER current HEAD!*
[user at localhost heads]$

Genesis was on October 18th, 2018 (git clone -b rocko git://
git.yoctoproject.org/poky.git), so the command:
git checkout -B master origin/master created today (Dec 21st, 2018) master
HEAD file in .../.git/refs/heads .

Then I again bitbake core-image-sato, worked as a charm.

Thank you again,
Zoran
