Hi all,
After installing Fedora 26 on a Raspberry Pi 2 I modified the default install somewhat. Since I use a 32 GB SDcard, thereś plenty of extra space I replaced the swap partition for an LVM2 partition to put swap, /home, /var/log, /var/log/audit on a separate partition. (used gparted to do so)
This all seems to work fine but when /tmp is put on an LVM-partition boot will fail:

The root-partition will mount read only during boot when /tmp is on a separate (LVM) partition. Now, after booting:
- mount -o remount,rw /
- mount -a
and all will work fine be shouldn't be that way....
What going wrong here....?
I have no idea but if I was to guess I suspect the initird doesn't have the lvm related components to enable it to mount tmp on that type of filesystem stack (it is usually either tmpfs or on root) so you'll probably need a dracut config that adds the appropriate dracut and kernel modules into the initrd and then regenerate the initrd. "man 5 dracut.conf" will likely give you all the information you need.
