run level 1, login takes too long, 2.4.X vs. 2.2.X

run level 1, login takes too long, 2.4.X vs. 2.2.X

[M.H.VanLeeuwen]

I had occasion to "telinit 1" today and found that it took a long time
to login after root passwd was entered.  this doesn't happen with 2.2.X
kernels.

Is this to be expected with the 2.4 series kernels? or a bug?

It looks like login is trying to contact a YP server but getting no
response.  Was the kernel the only configuration detail you modified?

rpc.portmap isn't running, your login configuration/nss requires yp or something provided ans an RPC.

Hi David,

Yup, I know rpc.portmap isn't running, the point is that it wasn't running on either
2.2.17 or 2.4.X.  Isn't run level 1 supposed to only be the bare minimum of running
processes, a few kernel processes, init and getty.  No network services...

What's changed in the kernel to elicit this behavior?

Is there a better "faster" way to get root access at run level 1 w/o login & passwd
on 2.4.X?

No it's not an everyday occurance, but I was impatiently thinking the sytem had
locked up and rebooted a couple of times, so it got me wondering why 2.2.X and
2.4.X differ in this basic behavior.
