 Posted: Tue Oct 21, 2014 8:30 am Post subject: [SOLVED] Gentoo takes too much time to boot |
 |
|
Hi,
I had no any problem but after last system update I remarked (it may have happened before) that my Gentoo takes much more time to boot than before - about a minute instead of several seconds.
It isn't a critical problem but I'd like to understand the reason.
The most time is taken by the steps:
Waiting for uevents to be processed (about a minute)
Bringing up interface enp5s0f2 (about half a minute)
After system boots and I can't see a reason.
Last boot in rc.log

Better for analyzing:Are you having both interfaces, wired and wireless in the runlevel? AFAIR only the wireless needs to be in runlevel whereas the wired is started by netplug / ifplug. I may be mistaken as I haven't used the netifrc for quite some time.
Regarding the uevents matter, are you using rc_parallel="YES" in /etc/rc.conf? |

dmesg: http://pastebin.com/6MH7Euys
(some suspicious messages about failed firmware loading)
Yes, I have both interfaces running at the default. Should I remove the wired one? And for the wireless should it be net.interface_name at the default runlevel or rather wpa_supplicant?
No, I don't use rc_parallel="YES", rc.conf says it can be reason of boot lock. It may solve the problem? |

removing net.enp5s0f2 helped: bringing up the interface doesn't take time now. I still have to check whether it works on cable connection
But the problem with uevents still stays. |

If looking for easier setup read https://wiki.gentoo.org/wiki/Network_management_using_DHCPCD

I recall having had that problem before I changed to rc_parallel="YES". I've never gone back to unparallel. |

If you are using OpenRC, you might want to consider switching to eudev instead of udev.

RazielFMX, it worked. Except I have to get used again to the old names of interfaces.
charles17, parallel rc_parallel didn't help (but didn't make it worse neither), though dhcpcd is way better for me as network manager than netifrc. It's a pity I haven't seen this page before.
Thanks a lot both of you.
And I mark the topic as solved. |

I'm glad eudev worked for you!
The naming thing is odd, I use eudev and do not have the traditional eth0...
| Code: | $ ifconfig -a | head -1
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 |
I defer to someone more familiar with how this works.

sys-fs/eudev -rule-generator solved the problem. |

I completely forgot about that! I apologize! I had done the same thing when I first swapped to eudev (as per the how-to at the time I think).
| Code: |
$ grep eudev /etc/portage/package.*
/etc/portage/package.use:#sys-fs/eudev
/etc/portage/package.use:sys-fs/eudev -rule-generator
|
I'm glad everything is working for you at least.

Ah nice one guys, added the USE setting to the switching to eudev tip.
Does that mean we don't need udev-postmount in default, or is that always needed? |

You were supposed to remove udev-postmount from any runlevel for quite a while 
... unless you use eudev with rule-generator ofc. |

Yeah I have; I was asking about eudev.
| Quote: | | ... unless you use eudev with rule-generator ofc. |
which was the question. Thanks.
I sincerely doubt anyone using eudev is going to want that crap, but I'll note it for transition. |
