Broken build with "text file busy"

[yajo]

Current master build is failing with this log:

Traceback (most recent call last):
  File "/opt/odoo/common/build", line 26, in <module>
    subprocess.check_call(command)
  File "/usr/lib/python2.7/subprocess.py", line 535, in check_call
    retcode = call(*popenargs, **kwargs)
  File "/usr/lib/python2.7/subprocess.py", line 522, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child
    raise child_exception
OSError: [Errno 26] Text file busy
ERROR: Service 'odoo' failed to build: The command '/opt/odoo/common/build' returned a non-zero code: 1

Failure is a little bit random, but happens often. A possible workaround is to sync after chmod as explained in moby/moby#9547 (comment).

It was supposed to be fixed in eecb827 and ab0e261, but recent builds seem to be having the same problem again, so I'm reopening.

Would it be stupid to try something simple like a sleep 10?

[yajo]

Maybe that would work... stupid solutions for stupid problems 😆

I'm seeing another workaround in moby/moby#9547 (comment), maybe I'll try that before.
