Various BSD-derived operating systems including macOS and FreeBSD
require that ping6 be used for IPv6 destinations. The "ping" command
does not understand an IPv6 destination.
FreeBSD 13.x and later do handle IPv6 in the regular ping command,
but also retain a ping6 command. We use ping6 on all versions of
FreeBSD.

58ab66ec51 added LDAP support
for #4945 by shelling out to getdent.
It was supposed to fall back to the old method when getdent wasn't
found, but some variable name confusion (uid vs username) meant the
old path wasn't calling the right lookup function (user.LookupId
instead of user.Lookup).
Which meant that changed probably also broke FreeBSD and macOS SSH
support in addition to the reported OpenWRT regression.
The gokrazy support didn't look right either.

The retry logic was pathological in the following ways:
* If we restarted the logging service, any pending uploads
would be placed in a retry-loop where it depended on backoff.Backoff,
which was too aggresive. It would retry failures within milliseconds,
taking at least 10 retries to hit a delay of 1 second.
* In the event where a logstream was rate limited,
the aggressive retry logic would severely exacerbate the problem
since each retry would also log an error message.
It is by chance that the rate of log error spam
does not happen to exceed the rate limit itself.
We modify the retry logic in the following ways:
* We now respect the "Retry-After" header sent by the logging service.
* Lacking a "Retry-After" header, we retry after a hard-coded period of
30 to 60 seconds. This avoids the thundering-herd effect when all nodes
try reconnecting to the logging service at the same time after a restart.
* We do not treat a status 400 as having been uploaded.
This is simply not the behavior of the logging service.

The subshell in which gocross gets built cd's to the corp checkout dir
near the top, so all future references to corp repository files should
be simple relative paths, and not reference $repo_root. When $repo_root
is an absolute path, it doesn't matter and everything works out, but on
some OSes and shells and invocations, $repo_root is a completely relative
path that is invalidated by the "cd".

in commit 6e96744, the tsd system type has been added.
Which will cause the daemon will crash on some OSs (Windows, darwin and so on).
The root cause is that on those OSs, handleSubnetsInNetstack() will return true and set the conf.Router with a wrapper.
Later in NewUserspaceEngine() it will do subsystem set and found that early set router mismatch to current value, then panic.
expvar can only be defined once, so running tests with a repeat counter
will fail if the variables are defined inside of the test function.
