Description Jason Montleon 2019-04-08 21:05:12 UTC 
Description of problem:
fuse-overlayfs contains /usr/lib/modules-load.d/fuse-overlayfs.conf with the contents 'fuse'. This causes systemd-load-modules to fail with kernel 5.0.6

Version-Release number of selected component (if applicable):
fuse-overlayfs-0.3-8.dev.gita6958ce
kernel-5.0.6-300.fc30.x86_64

How reproducible:
Seems always

Steps to Reproduce:
1. Install Fedora 30
2. Install fuse-overlayfs
3. Reboot

Actual results:
Service fails with an error message to the effect, Failed to lookup alias 'fuse'

Expected results:
systemd-modules-load starts normally

Additional info:
worked around it for now by uninstall fuse-overlayfs
Comment 1 Giuseppe Scrivano 2019-04-09 07:59:37 UTC 
Dan, should we drop the patch for loading the fuse module?
Comment 2 Daniel Walsh 2019-04-09 11:25:43 UTC 
Is the fuse module always loaded?  Has the fuse module been renamed?
Comment 3 Jason Montleon 2019-04-09 14:07:40 UTC 
The module is still called fuse.

$ lsmod | grep fuse
fuse                  131072  7
Comment 4 Giuseppe Scrivano 2019-04-09 14:23:54 UTC 
looks like a selinux issue:

type=AVC msg=audit(1554819688.831:386): avc:  denied  { read } for  pid=3180 comm="systemd-modules" name="modules.softdep" dev="dm-0" ino=788279 scontext=system_u:system_r:systemd_modules_load_t:s0 tcontext=unconfined_u:object_r:modules_dep_t:s0 tclass=file permissive=0


Jason, could you try again with selinux disabled?
Comment 5 Jason Montleon 2019-04-09 15:40:25 UTC 
Yes, good catch, booting in permissive it works.

I see these:
