Our variants print stack traces on failures. This will make locating
errors much easier.

Previously, the Hurd included a translator providing /dev/random and
/dev/urandom based on a source copy of the random number generator
found in classic GnuPG.
The new random translator is using the SHAKE128 algorithm from the
SHA-3 family as the underlying cryptographic primitive. Being a
sponge construction, it allows the extraction of arbitrary amounts of
pseudorandom data. It is continuously fed entropy by hashing system
state that is hard to predict.

* sutils/MAKEDEV.sh (random): Create node.
(urandom): The new translator is both secure and non-blocking. Create
a link from urandom to random for compatibility with Linux.
* trans/Makefile (targets): Add 'random'.
* trans/random.c: Move the skeleton of the old random translator here,
but replace the PRNG with SHAKE128. Remove all dubious attempts of
accounting for entropy. Do not block ever.

Previously, a Subhurd's tasks were shown as weird processes in the
Motherhurd. This change connects the proc server in the Motherhurd
with the proc server in the Subhurd, embedding the Subhurd's process
hierarchy. Subhurd's processes can now be inspected and debugged like
any other process.
* NEWS: Update.
* boot/boot.c (mach_msg_forward): New function.
(boot_demuxer): Forward messages arriving on the new task notification
port from the proc server, and forward them to the proc server inside
the Subhurd via the notification port.

namespace to the Subhurd's proc server.

Previously, boot handed privileged kernel ports to Subhurds. This
made boot unusable for unprivileged users, and allowed Subhurds to
wreak havoc on the whole system. Fix this by handing out pseudo ports
instead of the privileged ports.
* NEWS: Update.

(allocate_pseudo_ports): New function.
(main): Handle new flag. If not running privileged, allocate more
pseudo ports to hand out in place of privileged kernel ports, create a
task namespace, and a task that the Subhurd can frob instead of the
real kernel task.

that there have been a lot of them! This only documents changes made until
Jan 2001, and only changes to the applications, not to the libraries.
It still holds that this needs more work, trolling through ChangeLogs.
