[Bug 1859483] [NEW] busybox udhcpd does not honour SIGTERM

[Rasmus Villemoes]

Public bug reported:

busybox 1.27.2, shipped with at least Ubuntu 18.04, has a bug where the
udhcpd daemon does not react properly to SIGTERM.

That bug if fixed in upstream busybox as of 1.29.0, commit
3293bc146985c56790033409facc0ad64a471084 . That patch should be back-
ported to the busybox 1.27.2 - I believe it applies cleanly (it did when
we hit this on our Yocto-based embedded systems).

** Affects: busybox (Ubuntu)
     Importance: Undecided
         Status: New
