[solved] how to solve udev block with systemd

luna80 · Last edited by luna80 on Thu Aug 28, 2014 6:03 pm; edited 1 time in total

I'm on a fresh installation, and I'm follow this wiki http://wiki.gentoo.org/wiki/Systemd

but I can't solve the problem of the udev block, I don't understand what to do...

I tried to unmerge udev but util-linux failed to compile because tell that libudev is required but not found.

Any help is appreciated, thanks in advance

Hi luna80

you may find the instructions in this section of my EFI Gentoo End to End Install guide on the wiki useful.

To summarize here, the two-stage install of sys-apps/dbus/ and sys-apps/systemd is no longer necessary; the circular dependency on sys-fs/udev-init-scripts-25 was broken by moving it to PDEPEND, as of revision 1.9 of the systemd-208-r2.ebuild.

As such, once you have set your profile correctly, you should be able simply to:

Well, it built, so you're making progress ^-^

However, per the wiki page you originally quoted, to get systemd to actually function, there are a few other things you need to do (in your chroot environment - you'll need first to reboot your system using the Gentoo minimal install image, then re-enter the chroot):

ensure the appropriate options are set in your kernel, and rebuild it if not (per these instructions)
make sure /etc/mtab is a link to /proc/self/mounts (per these instructions)
ensure that the kernel hands off to the correct init program (set init=/usr/lib/systemd/systemd as a command line parameter in grub), per these instructions (I assume you are not building an EFI system? Or one with any LVM/LUKS/initramfs? If any of that is not the case, please advise)

For the last of these, if you select the item on the grub menu and press "e" you can edit the command line to test it out. Remove any "quiet" from the line also, so you can see some debug output.

Once you have systemd booted, make sure to set up its configuration. I have some info on that here; see also here.

Let me know how you get on!

I don't found what I'm doing wrong, I think is all ok your steps

the bigger problem is that I don't have the possibility to check for errors, at the reboot it appear the grub menu and after only the black screen with the sentence

Loading Linux 3.14.14-gentoo ...

and nothing else

If you hit 'e' when you select the boot option in grub, what kernel command line does it show?
(it may be a modesetting problem)

And just to confirm, this isn't an EFI install, it that true? (Because otherwise, it might be a problem with secure boot, see this post for example...)

Have you tried appending nomodeset to the end of the 'linux' line (from the 'e' screen in grub), then booting it with ctrl-x?

What happens if you try it with

OK, so it looks like you are in systemd's emergency mode: usually that's because something in /etc/fstab didn't mount or failed an fsck (which tallies with the error message you reported).

See for example this post.

I don't know your partition layout, but at a rough guess, since it is complaining about EXT4-fs (sd4), you may have written sd4 rather than sda4 in your /etc/fstab somewhere? If so, change this (use vi or nano as root, from the emergency mode) and try "systemctl default" again. Then configure systemd as described in my earlier post.

PS Don't forget to add any changes to grub to your grub config once happy with them (see this Archlinux wiki article for some pointers). Otherwise you'll have to do the 'e - edit - ctrl-x' thing each time you boot.

I'm so stupid

in the fstab file I put sda4 rather than sda5, fixed this and set to text the GRUB_GFXPAYLOAD_LINUX configuration now all works!

thanks a lot sakaki, you helped me very much, you're very kindly!!

Hi Gregory,

apologies, I missed your post, as it was appended to a thread marked 'solved'.

Did you manage to resolve the problem?

Ok, so just tried this out: doing the post-profile-set @world upgrade on a fresh install (with all previous steps carried out per the tutorial's instructions) shows me:
