Option '-w 100' of flock is failsafe to finish if dead lock occurs. It should be impossible to occur dead lock. And option '-w' is not supported by busybox, so remove it.

# This bbclass provides basic functionality for user/group settings.

|
# This bbclass is intended to be inherited by useradd.bbclass and

|
# extrausers.bbclass.
|

|
|
# The following functions basically have similar logic.
|
|
# *) Perform necessary checks before invoking the actual command
|
|
# *) Invoke the actual command with flock
|
|
# *) Error out if an error occurs.
|
|
|
|
# Note that before invoking these functions, make sure the global variable
|
|
# PSEUDO is set up correctly.
