Hi list,
running this python3 script:
#!/usr/bin/env python3
import psutil
pids = psutil.pids()
for i in pids:
p = psutil.Process(i)
with p.oneshot():
print(str(i) + " " + p.name())
The result start with:
0 swapper
1 init
536 smtpd
868 ksh
...
This process does not appear in ps, top and htop.
$ ps -p 0
PID TT STAT TIME COMMAND
0 ?? DK 0:02.19 (swapper)
For top, you need to press S to show system processes. I don't use
htop, but I assume it has a similar capability to show system processes.
How could be that there is a process with PID 0 before init?
Probably I'm missing something about OpenBSD core.
Can someone point me in the right direction?
See uvm_init(9):
The swapper process swaps in runnable processes that are
currently swapped out, if there is room.
... and this is a lie. The swapper process does nothing.
Ok, but why it is running?
