Previously on large server(s), there was an issue where because
chunkloaded computers all started up at once, so they all had the same
discovery message sending timer. This prevents that by starting each off
with a random offset. Also increases the interval for sending messages
from 15 s to 30 s, so that messages (which are the same, a lot of the
time) get sent less often.
Prevent labels from having .., /, *, control characters, or quotes (this
generally messes things up) and limit them to a reasonable length. We
might possibly also want to do this in snmp.lua, I'm not sure if that
will break things though
Make genotp more clearly state that the password can be used once but
allows permanent access (sorry for not making this clear earlier.) Use a
slightly longer password, and allow uppercase characters except for some
that could be ambiguous
This commit adds a one-time password system. Users can generate
passwords by using the `genotp` command (or manually queuing a set_otp
event with the SHA-256 hash of the one-time password they want to set)
and these passwords will be valid, along with the normal password,
either until the computer shuts down (or the net daemon is killed), a
new one-time password is generated, or the one-time password is used.
Changed the way processes are launched.
multishell.openTab and kernel.run now accept the current environment as a parameter.
That new process inherits a copy of the passed environment.
Reduces complexity as the calling process is not required to create a suitable env.
Stack traces have been greatly improved and now include the stack for coroutines that error.
