An update on this. Gtk3 reads /etc/fstab. This is my /etc/fstab:
Code: Select all
none /proc proc defaults,noatime 0 0
none /sys sysfs defaults,noatime 0 0
none /dev/pts devpts gid=2,mode=620,noatime 0 0
shmfs /dev/shm tmpfs defaults,noatime 0 0
If I comment-out one of those lines, by prepending a "#", it disappears from the gtk3 dialog window.
Or, change /etc/fstab to an empty file, they all disappear.
I could just get rid of /etc/fstab. For a very long time, from the days when I was building pups, then quirky, then easyos, I considered /etc/fstab to be deprecated. Don't need it, could drop it completely.
However, I would rather find out how to tell gtk3 not to read those entries.
