Description of problem: I have installed dnf plugin for snapper - to automatically store snapshots. After installing a single package an error occured. Looks like the problem is about '/.snapshots/1' SELinux is preventing snapperd from 'create' accesses on the directory 1. ***** Plugin catchall_labels (83.8 confidence) suggests ******************* If you want to allow snapperd to have create access on the 1 directory Then you need to change the label on 1 Do # semanage fcontext -a -t FILE_TYPE '1' where FILE_TYPE is one of the following: snapperd_conf_t, snapperd_data_t. Then execute: restorecon -v '1' ***** Plugin catchall (17.1 confidence) suggests ************************** If you believe that snapperd should be allowed create access on the 1 directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep snapperd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:snapperd_t:s0-s0:c0.c1023 Target Context system_u:object_r:unlabeled_t:s0 Target Objects 1 [ dir ] Source snapperd Source Path snapperd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-158.2.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.3.3-300.fc23.x86_64 #1 SMP Tue Jan 5 23:31:01 UTC 2016 x86_64 x86_64 Alert Count 1 First Seen 2016-01-24 12:42:03 MSK Last Seen 2016-01-24 12:42:03 MSK Local ID 5a31c0bb-85a6-4018-a17c-01e324ee3b52 Raw Audit Messages type=AVC msg=audit(1453628523.365:3603): avc: denied { create } for pid=15394 comm="snapperd" name="1" scontext=system_u:system_r:snapperd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:unlabeled_t:s0 tclass=dir permissive=0 Hash: snapperd,snapperd_t,unlabeled_t,dir,create Version-Release number of selected component: selinux-policy-3.13.1-158.2.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.3.3-300.fc23.x86_64 type: libreport
Description of problem: Install Fedora with btrfs file system and install snapper. Create Snapper configuration for root subvolume: # snapper -c -root create-config / Make a snapshot # snapper -c root create Note that Snapper managed to create the directory /.snapshots/ but actual snapshot creation fails.

Yes, it's a known problem. snapper (with btrfs backend only) snapshots directories have invalid selinux type set for subtree after ioctl call. *** This bug has been marked as a duplicate of bug 1247530 ***
