[OE-core] [PATCH 0/1] Replace retry logic in useradd with flock

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

Hi Ross,

We met problems that useradd fails to add users. I found it a simultaneous issue, so created this patch.

As a comparison of build time:

Without flock:
1
$ time bitbake core-image-minimal

real    38m8.625s
user    318m43.262s
sys     62m47.710s


2
$ time bitbake core-image-sato

real    54m13.065s
user    587m1.386s
sys     122m16.949s



With flock:
1
$ time bitbake core-image-minimal

real    40m55.178s
user    316m26.576s
sys     58m53.322s


2
$ time bitbake core-image-sato

real    55m11.312s
user    580m16.787s
sys     118m16.385s
