  • [gentoo-user] Help with dracut, please

    From Peter Humphrey@21:1/5 to All on Wed Oct 26 16:30:01 2022
    Hello list,

    I'm installing Gentoo on a new Juno laptop, and I've reached the point of booting into the new system. I have a separate /usr partition and I'm using dracut to create an initramfs.

    On booting the new system I get an error I haven't heard of before: dracut complaining "sysroot has no proper sysfs layout". I'm sure I've done something stupid, but where do I start debugging this? Google hasn't helped.

    I tried to google that message and it found nothing.  That's not good. 
    Makes me wonder what is causing that.  Made me think a bit. 

    Have you double checked your fstab?  Maybe you missed updating a line,
    missed commenting something out or a typo maybe?  Any strange kernel
    options added to your bootloader?  Typo maybe?  Have you double checked
    that the file systems you use for /boot and / are built into the kernel? 

    Hopefully someone else will have more ideas but in the meantime, may
    want to double check those.  Just to be sure. 

    Hope that helps, or someone else has ideas.

    Dale

    ^^This^^

    Otherwise it may be some corrupt fs, in which case fsck could help.

    Is CONFIG_SYSFS=y set in your kernel?

    Yes. I don't see it in menuconfig, but a search for it says it's set by a boolean expression that evaluates to TRUE.

    I was right the first time: it was something I'd done - a typo in /boot/loader/ entries/<entry>. (My eyes just get worse all the time. That's my excuse and
    I'm sticking to it.)

    Now, though, the system gets as far as populating /dev and hangs. So, back to SysRescCD and check that devfs is selected, and it is. I'll go through the kernel config yet again and see what I may have missed.
