That’s weird indeed. Nautilus intends to display mount points (this is
from nautilusgtkplacesview.c):
--8<---------------cut here---------------start------------->8---
static void
update_places (NautilusGtkPlacesView *view)
{
[...]
/* Add currently connected drives */
drives = g_volume_monitor_get_connected_drives (priv->volume_monitor);
[...]
/*
* Since all volumes with an associated GDrive were already added with
* add_drive before, add all volumes that aren't associated with a
* drive.
*/
volumes = g_volume_monitor_get_volumes (priv->volume_monitor);
for (l = volumes; l != NULL; l = l->next)
[...]
/*
* Now that all necessary drives and volumes were already added, add mounts
* that have no volume, such as /etc/mtab mounts, ftp, sftp, etc.
*/
mounts = g_volume_monitor_get_mounts (priv->volume_monitor);
for (l = mounts; l != NULL; l = l->next)
{
GMount *mount;
GVolume *volume;
mount = l->data;
volume = g_mount_get_volume (mount);
if (volume)
{
g_object_unref (volume);
continue;
}
add_mount (view, mount);
}
/* load saved servers */
populate_servers (view);
[...]
}
--8<---------------cut here---------------end--------------->8---
However, ‘g_mount_get_volume’ is expected to return NULL for “system
mounts”. GLib’s gunixmounts.c attempts to determine whether a mount
point is a system mount by checking its file system type and mount
point:
--8<---------------cut here---------------start------------->8---
gboolean
g_unix_is_mount_path_system_internal (const char *mount_path)
{
const char *ignore_mountpoints[] = {
/* Includes all FHS 2.3 toplevel dirs and other specialized
* directories that we want to hide from the user.
*/
"/", /* we already have "Filesystem root" in Nautilus */
"/bin",
"/boot",
"/compat/linux/proc",
"/compat/linux/sys",
"/dev",
[...]
NULL
};
if (is_in (mount_path, ignore_mountpoints))
return TRUE;
if (g_str_has_prefix (mount_path, "/dev/") ||
g_str_has_prefix (mount_path, "/proc/") ||
g_str_has_prefix (mount_path, "/sys/"))
return TRUE;
if (g_str_has_suffix (mount_path, "/.gvfs"))
return TRUE;
return FALSE;
}
static gboolean
guess_system_internal (const char *mountpoint,
const char *fs,
const char *device)
{
const char *ignore_fs[] = {
"auto",
"autofs",
"devfs",
"devpts",
"ecryptfs",
"fdescfs",
"kernfs",
"linprocfs",
"mfs",
"nullfs",
"proc",
"procfs",
"ptyfs",
"rootfs",
"selinuxfs",
"sysfs",
"tmpfs",
"usbfs",
"nfsd",
"rpc_pipefs",
"zfs",
NULL
};
const char *ignore_devices[] = {
"none",
"sunrpc",
"devpts",
"nfsd",
"/dev/loop",
"/dev/vn",
NULL
};
if (is_in (fs, ignore_fs))
return TRUE;
if (is_in (device, ignore_devices))
return TRUE;
if (g_unix_is_mount_path_system_internal (mountpoint))
return TRUE;
return FALSE;
}
--8<---------------cut here---------------end--------------->8---
This rule should let /gnu/store through, but it should clearly exclude
/proc, /sys, /run/systemd (tmpfs), etc.
I think we’ll have to attach gdb to nautilus to understand what’s going on.

Regarding auto-mount, I’ve noticed that “touching” the device node (as
in “cat /dev/sr0 > /dev/null”) triggers the auto-mount and UI
notification.
Does anyone know the big picture better?

Hello,
I use i3 window manager myself and have solved this problem by
installing gvfs package in my guix profile.
I started the nautilus file manager from the terminal emulator and I got
the following warnings:
invoking IsSupported() failed for remote volume monitor with dbus name
org.gtk.vfs.UDisks2VolumeMonitor::
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name org.gtk.vfs.UDisks2VolumeMonitor was not provided by any
.service files (g-dbus-error-quark, 2)
invoking IsSupported() failed for remote volume monitor with dbus name
org.gtk.vfs.MTPVolumeMonitor::
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name org.gtk.vfs.MTPVolumeMonitor was not provided by any
.service files (g-dbus-error-quark, 2)
invoking IsSupported() failed for remote volume monitor with dbus name
org.gtk.vfs.GPhoto2VolumeMonitor::
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name org.gtk.vfs.GPhoto2VolumeMonitor was not provided by any
.service files (g-dbus-error-quark, 2)
The gvfs package provides the above mentioned dbus services.
To test this I installed it to my user profile by running:
guix package -i gvfs
I had to check the presence of the above mentioned dbus service files by
running:
ls -l $GUIX_PROFILE/share/dbus-1/services/
And since I have fish as my default shell I had to run:
exec sh -c "source $GUIX_PROFILE/etc/profile; exec fish"
to properly set new environment variables.
(You can change the above command by replacing 'fish' with your shell
command.)
At this point I started nautilus from the terminal emulator and the
problem was solved.
Test this solution and of course you can add this package in your system
profile.
This reply is a bit late but it may be useful to others who have similar
problems.
