Thank you very much for looking into this! Does the following information help to make head or tail of this? Otherwise, I will provide better instruction for reproduction.

I have. ls -la /dev/fuse crw-rw-rw- 1 0 0 10, 229 Aug 29 07:10 /dev/fuse fuse installation, - works with only /dev mounted in chroot - works with only /proc mounted in chroot - does not work with both, /dev and /proc mounted in chroot It is mounted using: mount --bind "/dev" "$CHROOT_FOLDER/dev" mount --bind "/proc" "$CHROOT_FOLDER/proc" > As noted above, if the fuse device is not there, the udevadm is not > run due to the check for that being false. One thing came into my mind > is that you have the chroot on a mount point that has the nodev > option. Can you check that please? By the time this bug happened, nodev was not in use. (Maybe nodev will be used in the future if that is possible.)
