OpenRC and baselayout 2 - Stunning!

OpenRC and baselayout 2 have just hit ~x86 and I've got to say I am absolutely stunned how quick the startup time is now. Just a word of warning, if you are like me and run a ~x86 system and regularly update it without paying the utmost attention to what's being updated you do want to take a look at this, http://www.gentoo.org/doc/en/openrc-migration.xml.

Great work!

Good stuff.
I was thinking about this after seeing that post on the Gentoo front page. I was thinking maybe its an idea to put in my own mask into my /etc/portage/package.mask file in order to avoid surprises. Then remove the mask again when I am ready to update that part.

I'll probably just try to remember it when I run world updates next time, in few weeks.

For now, I'd heartily recommend masking baselayout-2 and OpenRC. I am still ironing out the bugs that came with that "upgrade". I got lucky with my 64 bit system since it only uses one network interface. However, my laptops need to be able to rename their net interfaces, and that ain't happening with this new setup. For the time being, I have things functional on two out of three systems. I am debating whether I should go for an update on the third, or whether I should leave it until the bigger kinks are removed from this system. I am leaning towards not.

Frankly, I don't see a whole lot of difference. Perhaps sometime in the future I will. For now, color me unimpressed.

Blessed be!

there was a few issues on my system but i managed to get all of them fixed and now it all works great and is a lot faster, good job!

all good here, been running it for a while now on the x86, just upgrading 64 bit now - migration guide is good.

I just removed baselayout-2 from this machine (a three hour tour of hell). It prevented my automatic networking script from operating, and caused a few other irritations.

While I understand the idea behind the new baselayout, I'm unimpressed with the results I've seen on my laptop thus far. I am going to leave it on my Core2 because that machine has only one network interface, and it wasn't bothered in the least by the upgrade.

Blessed be!

I have to say that i have mixed feelings about the new gentoo init-system. On one hand it's ALOT faster than the old one on the other i experience quite alot of bugs with the new system: First of all i compiled almost all my drivers as modules that includes rtc_cmos for my system's realtime clock, so i experienced problems with the hwclock-initscript as it was started before modules-initscript was (before * in the init-script). That was easy to fix just replace before * with after modules and that was it. The other problem is really annoying: Whenever i actually log into X and try to shutdown/reboot openrc fails to stop xdm-initscript and hangs on dbus-initscript. If i don't log into X rebooting/shutting down the system works as expected. Only thing that helps is using SysReq: emergency reboot to reboot the system. Anybody else experienced this problems and found a solution?

Well, I'm trying to get this working on my test box, but it's dying.

Perhaps I can get some help? On reboot, I'm getting the following message:

Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy and press ENTER

VFS: Cannot open root device "sda3(then a bunch of weird symbols for almost a full line, like half an H)" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:
0800 160836480 sda driver: sd
0801 136521 sda1
0802 3911827 sda2
0803 156786367 sda3
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

And here is my menu.lst in grub:

default 0
timeout 1

title=Gentoo 2.6.24-gentoo-r4
root (hd0,0)
kernel /boot/bzImage root=/dev/sda3

Any ideas?

I haven't changed anything in grub, so I'm not sure why this migration to OpenRC started this mess, heh.

Did you update Grub, too? I've been having problems with -r5. I ended up reverting to -r4.

tsuehpsyde · Post by **tsuehpsyde** » Thu Apr 17, 2008 4:49 pm

I'm not sure. I rebooted and it randomly booted up to OpenRC and started up. I simply rebooted, and it got stuck again. Something is definitely flakey...

pappy_mcfae · Post by **pappy_mcfae** » Thu Apr 17, 2008 5:01 pm

The speed with which my computer boots is immaterial to me. I'd say 45 seconds from start to finish is live-with-able. And even if openrc slims that down to 30 seconds, it's not worth the savings if I lose functionality. The good thing is you can remove the new baselayout and openrc. Doing that has brought my laptop back to the kind of functionality *I* want. After all, that is one of the main reasons I remain a Gentoo user.

Blessed be!

Simba7 · Post by **Simba7** » Thu Apr 17, 2008 5:20 pm

I haven't bumped into the loss of functionality... but I did redo all my systems when I switched over..

cyrillic · Post by **cyrillic** » Thu Apr 17, 2008 7:13 pm

I must admit, I was scared to take the plunge into openrc/baselayout2

... but I did it anyways, and I am quite pleased with the results.

I reboot my deskside when I update the kernel. Other than that, it's here when I need it, and increasing its uptime when I'm not. I'm pretty much completely uninterested in the boot time on this machine.

My laptop, on the other hand, is a different case. I'd like to see faster boots there. But of course it also has 2 network (wired and wireless) interfaces, so I may bump into the problems others have had. I also have my own post-networking script that makes extensive changes, including runlevel, ( runlevels for home, work, nonetwork, travel, etc ) based on the issued IP address. That sounds like it may need rework.

Does the new /etc/conf.d/net.example show how to add an extra static route, like the old one did?

After rebooting 2 of several boxes, I have to agree: stunning.

I'm not sure. I looked at it, and when I didn't find the ability to rename my interfaces, I decided it wasn't for me. Part of the problem for me is for some reason, my auto-networking script just stopped working. Gone...history...no more. Untying the knots was a total P.I.T.A. Perhaps I'll give it a go when they get the bigger bugs out. For now, as I said before, color me unimpressed.

And like you, curiously, the only machine that took the upgrade without completely falling to pieces was the machine I hardly ever reboot. Hmm.

Blessed be!

Given the warning, I think I'll have /etc backed up before starting this. I have a spare machine that I may try the baselayout-2 on this weekend, just to get a feel.

That would be an incredibly wise thing. Unfortunately for me, I updated two machines at once, not realizing what was going to happen. That was a mistake.

Blessed be!

I don't care how fast I boot up. No matter what 5-20 seconds got trimmed off of that it was not worth the 6+ hours of trouble shooting to get the damn thing running.

Maybe you just didn't know where to look.

Renaming interfaces can be done easily by editing /etc/udev/rules.d/70-persistent-net.rules

I agree.. One of my boxes is a router/firewall. The less time it has to reboot, the more happy I become.

I know. I edited said file so my wired adapter starts life as wth0. My wireless naturally starts life as wlan0. Then, I have a script that looks for carrier on the wired adapter. If it is found, wth0 is then renamed to eth0. If not, then wlan0 is renamed to eth0. It works flawlessly. And, it works the way *I* want it to.

When I move to baselayout-2/openrc, the script shuts down and renaming the interfaces goes out the window. That is NOT how I want my machine to work. Part of what I like most about Gentoo is that I decide how the computer operates, not the other way around. If I want the computer to tell me how *it* wants to work, I can always boot into Windoze XP.

So, when and if an option comes into being with the new setup that will allow me to continue to use my computer the way I want to use it, I'll gladly switch. Until that time comes, I'm not interested.

Thanks.

Blessed be!
Pappy

I really would have appreciated it if a completely unmasked (okay, in ~amd64 but still) package would not delete my /etc/conf.d/net without even showing up in etc-update...

Even if it can't handle the old format, the least it could do is move it out of the way instead of just overwriting it with an empty file...(happened to me on three computers so I am pretty sure I didn't accidently do that via etc-update)

Treggats · Post by **Treggats** » Sat Apr 19, 2008 10:23 am

I must say, the new baselayout is stunning, everytime I boot or shutdown my laptop I'm amazed by the speed at which it goes.
I've had no problems with network adapters, since I only let net.lo boot. The others will start when I log in (networkmanager)

Even though it was quite scary to do the upgrade, as I *might* wreck my system. After the reboot all was fine and fast

The thing I didn't understand was if I was supposed to put all my old /etc/conf.d/rc into the new /etc/rc.conf

In the following line:

add a [space] at the end, it is a bug from the latest grub.
