** Description changed:

- My sshfs mounts from /etc/fstab stopped working after upgrading to
- Plucky. This is the line from my fstab:
+ [ Impact ]
+ 
+ sshfs mounts specified in /etc/fstab would fail to mount when a mount of
+ all filesystems specified in the fstab was attempted with mount -a. This
+ was due to a missing noexec mount flag specification in the mount rules.
+ 
+ [ Test Plan ]
+ 
+  * The setup instructions assume no access to an existing SSH client-server 
pair.
+    - Spin up two Ubuntu Plucky VMs, one of which will be referred to as 
sshfs-client and the other of which will be referred to as sshfs-server
+    - Install openssh-server on the server and sshfs on the client
+    - Ensure that the two machines are able to ping each other using a 
[machine hostname].local address
+    - Generate an SSH key on the client and copy it into the 
~/.ssh/authorized_keys directory on the server
+    - Ensure that the client can SSH into the server without a password prompt 
(using the key)
+    - Uncomment the "user_allow_other" line in sshfs-client's /etc/fuse.conf
+    - Create a mountpoint directory somewhere inside sshfs-client's home 
directory
+    - Verify that a manual sshfs mount using `sshfs -o 
_netdev,user,idmap=user,transform_symlinks,allow_other,default_permissions,uid=1000,gid=1000
 username@sshfs-server:/path/to/directory /home/username/mountpoint` works, and 
then unmount the newly created mount
+    - Add the entry `username@sshfs-server:/path/to/directory 
/home/username/mountpoint fuse.sshfs 
_netdev,user,idmap=user,transform_symlinks,allow_other,default_permissions,uid=1000,gid=1000
 0 0` to sshfs-client's /etc/fstab
+    - Attempt to mount the new fstab mount entry with `mount -a`
+    - Without the fix: the mount will fail with a permission denied error and 
generate an AppArmor log with "failed flags match"
+    - With the fix: the mount should succeed
+    
+ 
+ [ Where problems could occur ]
+ 
+ Adding the mount flag to the mount rules loosens confinement on a
+ profile. However, if a user manually modified the installed profiles,
+ then the package upgrade would cause conflicts, and rejection of the
+ incoming changes (either by hand during an interactive upgrade or
+ automatically during an batch unattended upgrade) would result in end
+ users not getting the packaged fix.
+ 
+ [ Other Info ]
+ 
+ --------Original bug report:
+ My sshfs mounts from /etc/fstab stopped working after upgrading to Plucky. 
This is the line from my fstab:
  
  ```
  [email protected]:/datastore/media     /media/Media    fuse.sshfs   
   
_netdev,user,idmap=user,transform_symlinks,port=22,allow_other,default_permissions,uid=1000,gid=1000
    0       0
  ```
  
  And I uncommented `user_allow_other` in `/etc/fuse.conf`.
  
  Usually I'm able to mount this with `mount -a`, or by simply clicking
  the mount in Gnome Files (Nautilus). But now I get:
  
  ```
  mount -a
  fusermount3: mount failed: Permission denied
  ```
  
  If I add `sudo` to the mount command, I get:
  
  ```
  sudo mount -a
  read: Connection reset by peer
  ```
  
  But strangely, the mount works just fine if I mount using `sshfs`:
  
  ```
  sshfs -o 
_netdev,user,idmap=user,transform_symlinks,port=22,allow_other,default_permissions,uid=1000,gid=1000
 [email protected]:/datastore/media /media/Media
  ```
  
  I suspect it has something to do with apparmor, because the following
  log appears when I attempt a mount via Nautilus:
  
  ```
  sudo journalctl -xe | grep DENIED
  mei 27 13:58:51 saibot kernel: audit: type=1400 audit(1748347131.297:5484): 
apparmor="DENIED" operation="mount" class="mount" info="failed flags match" 
error=-13 profile="fusermount3" name="/media/Media/" pid=69641 
comm="fusermount3" fstype="fuse" 
srcname="[email protected]:/datastore/media" flags="rw, nosuid, 
nodev, noexec"
  ```
