This may be not core18 specific (or even chromium specific) but when I open file dialog (i.e. to import bookmarks) and select my {HOME} dir, then I have access denied logged for most my dotfiles. This is especially annoying when aa-notify is running on system as it causes the whole screen being filled with notifications.
Is it possible to explicitly DENY access to all dotfiles in apparmor profile so access to them won’t be logged?
There are also denials for /etc/fstab, /etc/mtab, /run/mount/utab.
This is tested on Ubuntu Bionic with Xfce.
