I am setting up a new root partition on /dev/sda2 (newer Fedora 25) I have done this before and had no problems in the past. (If you realy need to know how see Fedora on New Root Partition

This time however I get a "A start job is running for dev-disk-by..." error during the boot sequence.

It cannot be the UUID problems as I don't use them.

This is the /etc/fstab of the new root partition...

# /etc/fstab
#/dev/sda1 /        xfs     defaults        0 0
/dev/sda2 /        ext4    defaults        0 0
/dev/sda5 /home    xfs     defaults        0 0
/dev/sda3 swap     swap    defaults        0 0

Everything checks out. The FS types are correct. In fact this is the same "/etc/fstab" used on the previous (and working root partition, just with "/dev/sda1" as "/" and "/dev/sda2" as "/mnt/alt"

But I still get that error, hanging basically forever (I let it go for an hour!) As such every other answer I have seen is useless!


Boot a live installer and mount the install (including /boot and /dev,/proc/sys and chroot back in and rerun a dracut --regenerate-all --force && grub2-mkconfig -o /etc/grub2.cfg and then retry. The rational here is that teh grub image is still looking for the old data as it and the initramfs|initrd were never updated to look at the new locations and mappings.

  • The point of installing directly into an alternative root partition, is to avoid the requirement to set up a DVD (which the system does not have) or a USB stick. That is basically get the system in a working state before booting from the old to new system. Also keeping the old system in perfectly working (default) state while testing the new system, until you are ready for a full switch. So how can I get it to boot the old system and clear that confusion. Which did not happen on other systems I have done this with! – anthony Apr 19 '17 at 6:28
  • So how can I... set up the full chroot using the new root... so I can then properly regenerate the initial RAM disk – anthony Jul 19 '17 at 2:16
