diskless systems forget how to go multiuser?
I've seen the following behavior on a couple of systems I netboot and
Upon initial boot and mounting the freshly-populated NFS root directory,
all goes well and the machine operates normally. Even after a few
post-installation tweaks, rebooting the machine goes normally and it
returns to multiuser operation.
Then after a few cycles of this, on some subsequent boot, 'init' takes
a very long time to decide what to do and then behaves as if it had
been told to run in single-user mode (prompt user for shell). It then
does this for every boot thereafter.
At the single-user shell prompt, one can run 'sh /etc/rc' and have it
launch all the usual services, but it's still effectively in single-
user mode. 'exit'ing the single-user shell, 'init' again takes several
(10+?) seconds and then repeats the single-user shell query.
Even after updating with freshly-built install sets, the machine is
trapped in this state. (I have not yet restarted from scratch on
either machine I've observed, but perhaps I'll do that soon.)
I first saw this on an -current/i386 machine about a month ago. More
recently, I saw exactly the same behavior on an evbmips64-el machine
I have a couple of other -current/i386 and -current/macppc machines that
I run disklessly, but have not booted/updated them in a couple of (in
some cases many) months, so I don't know if this behavior is more
widespread and/or introduced by some changes in the meantime.
I don't have any machines running 6.0-BETA disklessly right now, but
I suppose I should check that too.
Machines booting from local disk appear to have no problems.
