Description

If uptime is invoked early in the boot process, it prints a message which is not quite right:

$ uptime
23:07:43    up  1 user,  load average: 0.30, 0.08, 0.03

Critically, the uptime is entirely absent -- it should be present between "up" and "1 user". Once at least a whole minute has passed, the output is correctly rendered.

here is the copy of uptime(1M) from my last patch and its output on a freshly booted server:

  • File deleted (uptime)

which then correctly prints out

[despair@sun-pc /data2/illumos-gate]$ sudo ./uptime
00:00:02    up 11 hr(s),  1 user,  load average: 0.21, 0.25, 0.21

(A full nightly would build a w(1M) that can be run by normal user. Sorry.)
