Checking nautilus sources, it uses GVolumeMonitor which is part of glib (gio).
That uses GUnixMountMonitor, and that checks /proc/mounts and fstab.
fstab is found like this:
static char *
get_fstab_file (void)
{
#ifdef HAVE_LIBMOUNT
return (char *) mnt_get_fstab_path ();
#else
#if defined(HAVE_SYS_MNTCTL_H) && defined(HAVE_SYS_VMOUNT_H) &&
defined(HAVE_SYS_VFS_H)
/* AIX */
return "/etc/filesystems";
#elif defined(_PATH_MNTTAB)
return _PATH_MNTTAB;
#elif defined(VFSTAB)
return VFSTAB;
#else
return "/etc/fstab";
#endif
#endif
}
libmount is part of util-linux, which has:
/**
* mnt_get_fstab_path:
*
* Returns: path to /etc/fstab or $LIBMOUNT_FSTAB.
*/
const char *mnt_get_fstab_path(void)
{
const char *p = safe_getenv("LIBMOUNT_FSTAB");
return p ? : _PATH_MNTTAB;
}
In order to debug this problem, please try setting the environment variable
before starting nautilus, like this:
killall nautilus
export LIBMOUNT_FSTAB=/etc/fstab
nautilus
Then check whether detecting changes in CD/DVD state work fine like this.
