since Jessie, the udevadm binary is available as /bin/udevadm.
To not break existing scripts, which use the old /sbin/udevadm path,
the udev package currently ships a compat symlink which we would like
to drop eventually (in buster or buster+1).
According to codesearch  your package bit-babbler does hard-code the
udevadm path as /sbin/udevadm.
Please change that to /bin/udevadm.
Thanks for considering.

bit-babbler - BitBabbler hardware TRNG and kernel entropy source support
bit-babbler-dbg - debugging symbols for BitBabbler tools
bit-babbler (0.7) unstable; urgency=medium
* Handle the oddball case of a RHEL/CentOS 6 kernel being used with libusb
version 1.0.13 or later. They backported the USBDEVFS_GET_CAPABILITIES
API, but not the patch which was applied to the mainline kernel at the
same time to add USBDEVFS_CAP_BULK_SCATTER_GATHER. With the default
libusb 1.0.9 that it normally ships with this doesn't matter because none
of it is supported there anyway, but updating it makes this become a real
problem that we need to deal with.
* Test for SIGRTMIN, MacOSX doesn't have it.
* Test for pthread_setname_np by signature, it's implemented differently on
different platforms. Also support pthread_set_name_np which is what is
used by OpenBSD and FreeBSD.
* Explicitly set the pthread stack size on (more) platforms where it is tiny
by default. We do create some large structures on the stack, and it's
probably better to have a consistent size on all platforms than have some
of them smash it "unexpectedly".
* Querying the string length with strftime is a GNU extension, so only use
that where it's actually available.
* Provide an implementation of FeedKernelEntropy for MacOS. It does have a
documented interface for that, even if the implementation of it that is in
its kernel source as of Sierra is ... let's go with enlightening.
* Rename _P(), our convenience alias to ngettext, to P_(). On OpenBSD 6.1
_P is defined in ctype.h, and regardless of what you might think of that,
symbols starting with an underscore are reserved. So they win this one.
* Test for LOG_MAKEPRI, it isn't required by POSIX, and OpenBSD 6.1 doesn't
* Add explicit tests for strtod_l and newlocale. The newlocale function is
specified by POSIX, but OpenBSD doesn't provide it. We can get away with
falling back to strtod there because it only has very limited support for
locales anyway, and right now it will always be either C or en_US.UTF8,
both of which use '.' as the decimal point.
* Support systems without abi::__forced_unwind for thread cancellation stack
unwinding and clean up. The GCC toolchain on OpenBSD doesn't support it,
and neither does clang on FreeBSD or MacOS.
* Disable thread cancellation around calls to vfprintf on OpenBSD. On that
platform it is a cancellation point (as expected), but if cancellation
does occur there on 6.1, it can leave its internal _thread_flockfile mutex
locked which means any future calls to vfprintf (or anything else needing
that lock) will deadlock. We can't easily test for that bug, so we just
always provide our own safe cancellation point instead on that platform.
* Support unordered_map in both std and std::tr1 namespaces. Normally it
isn't available in std:: unless C++11 support is enabled, but clang on
FreeBSD provides the tr1 header as a symlink to the std one, and only
provides the template in the std namespace.
* Test for libusb_has_capability. FreeBSD 11 bumped LIBUSB_API_VERSION to
0x01000102, but didn't add the libusb_has_capability() function which was
part of that interface version. It did however add the hotplug API, and
it does mostly work, so if the API version is sufficient, but we can't
test for this capability, then we'll assume it's available and that it
will handle a call to it gracefully if for some reason it really isn't.
* Deal with FreeBSD 11 libusb start up and shut down delays. In our testing
there was a delay of around 4 seconds before it would report any existing
devices when LIBUSB_HOTPLUG_ENUMERATE was used with the hotplug callback
(and a similar delay when new devices really were hotplugged later). That
makes things awkward for the --scan option, which would see no devices at
all before returning its results, unless it too had an arbitrary (and user
unfriendly long) delay before responding. So we explicitly enumerate the
initial set ourselves on FreeBSD now even when hotplug support is enabled,
and handle any duplicates when the hotplug events finally do arrive.
Likewise, when libusb_exit is called, it also blocks for around 4 seconds
before returning - which delays our code from being able to do a clean
exit quickly. There's not much we can do about that one except add some
extra debug logging when verbosity is turned up, so that users can see it
is not actually our code that has them twiddling their thumbs waiting.
Hopefully later releases of FreeBSD will improve on this.
* Work around FreeBSD 11 deadlocking on device unplug. If a device is ever
removed while we are in the middle of a call to libusb_bulk_transfer(),
then that call may deadlock and never return, and the thread which called
it will not be able to be cancelled. We can limit the impact that has on
our code (since we will already always be cancelling that thread once we
get the hotplug notification of the removal) by using pthread_timedjoin_np
and if the join times out, bark about it and just ignore the zombie thread
that we've been left with. It's not ideal, and if it happens often enough
in a single process run, then leaked resources will start to be exhausted.
But most people don't replug things all that frequently, this won't happen
every time they do, and it is about the best we can do until the FreeBSD
bug is fixed. There's no downside to the workaround if the bug doesn't
actually occur when a device is unplugged.
* Disable some buggy optimisations (normally enabled by -O2) when using GCC
on FreeBSD 11. On that platform (we've not seen this anywhere else), they
appear to miscompile some code in a way that stack unwinding details are
lost and a thrown exception will invoke terminate rather than being caught
by the handler it should have unwound to. Some of these were in obscure
corners of the code that are only seen when unlikely errors occur, so it's
not impossible that there may be a few more lurking. But for now, we'll
just disable the known problem ones rather than falling all the way back
to compiling with -O0 on that platform.
* Add a --limit-max-xfer option to seedd and bbcheck. This gives people a
runtime workaround for systems where, despite having an ostensibly new
enough Linux kernel and libusb version to support large bulk URBs, the
hardware chipset has some quirk that isn't yet fixed in the kernel driver
which makes using them troublesome (I'm looking at you RPI3). If passed,
this will force the old 16kB limit on individual requests to usbfs. That
doesn't have any effect on the size of requests that users can make from
our code, it just might be slightly slower at obtaining huge numbers of
bits, since we need to get them in smaller chunks internally.
* Add an example of how to obtain random integers within an arbitrary range
where every value in that range remains equally probable. This isn't a
difficult thing to do, but enough people have asked to provide a working
example, and there's enough history elsewhere of people doing something
naive, like using a modulus to limit the range (thus making some values
more probable than others), to have a good example easily available that
users can refer to.
* Search for where udevadm is found in the qemu-hook script. Its installed
path was changed by systemd 204 in Jessie from /sbin to /bin, so now we
need to deal with multiple interfaces to stay portable, since there are
supported distro releases that aren't EOL yet which still have it in the
old location. Jessie's systemd had a compat link to make it available in
both places, but the systemd maintainers want to drop that for Buster (and
not all other distros with newer systemd provide that). Closes: #852582
* Tweak the udev rules to work around a bug in udev versions up to at least
232-25 which makes testing ATTR keys with != become a perilous folly. If
an event occurs for a device which does not have that attribute at all,
then the rule will be skipped, the same as if it was actually equal to the
value being tested for.
