Hello,
I use the noexec option for /home in fstab as per the security guidelines of the wiki https://wiki.archlinux.org/title/Security#Mount_options.
I mount /home/hadr/.local/share/flatpak to be able to use flatpaks. Here is how my fstab looks like
# /dev/sda8
UUID=eadf6911-32eb-44b2-a371-a17847ae4a7c /home ext4 rw,relatime,nodev,noexec,nosuid 0 2
# /home/hadr/.local/share/flatpak
/home/hadr/.local/share/flatpak /home/hadr/.local/share/flatpak none bind,nodev,exec,nosuid,nofail 0 0Unfortunately when I switch off my computer I have two errors telling that first /home/hadr/.local/share/flatpak cannot be unmounted because it is busy and subsequently a second one for /home for the same reason.
The output of lsof indicates that flatpak is preventing the unmounting.
sudo lsof | grep "/home/hadr/.local/share/flatpak"
[sudo] Mot de passe de hadr :

Why is the unmounting behaviour different between the two scenarios and how could I solve this keeping my /home with noexec option?
Thanks for the help.
