16 FWIW, I've always seen those entries (or something quite similar)
17 in /proc/mounts (for a long time), but never in the output of df.
18
19 $ cat /proc/mounts
20 rootfs / rootfs rw 0 0
21 /dev/root / reiserfs rw,noatime 0 0
22 proc /proc proc rw,nosuid,nodev,noexec 0 0
23 sysfs /sys sysfs rw,nosuid,nodev,noexec 0 0
24 udev /dev tmpfs rw,nosuid 0 0
25 devpts /dev/pts devpts rw,nosuid,noexec 0 0
26 /dev/sda7 /home ext3 rw,noatime,data=ordered 0 0
27 none /dev/shm tmpfs rw 0 0
28 none /proc/bus/usb usbfs rw 0 0
29
30 $ df

37 (I haven't switched to baselayout-2 yet). That said, I have no idea why
38 the output of df under baselayout-2 differs (although I assume that the
39 rc-svcdir thing is somehow related to baselayout-2 or openrc).
