Well on my x86 the inconsistency is not so bad to become a problem: root@hp:~# cat /etc/mtab /dev/root / ext4 rw,relatime,barrier=1,data=ordered 0 0 proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 usbfs /proc/bus/usb usbfs rw 0 0 /dev/sda1 /boot ext4 rw 0 0 tmpfs /dev/shm tmpfs rw 0 0
root@hp:~# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext4 rw,relatime,barrier=1,data=ordered 0 0 devtmpfs /dev devtmpfs rw,relatime,size=515692k,nr_inodes=128923,mode=755 0 0 proc /proc proc rw,relatime 0 0 sysfs /sys sysfs rw,relatime 0 0 devpts /dev/pts devpts rw,relatime,gid=5,mode=620 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 usbfs /proc/bus/usb usbfs rw,relatime 0 0 /dev/sda1 /boot ext4 rw,relatime,barrier=1,data=ordered 0 0 tmpfs /dev/shm tmpfs rw,relatime 0 0 root@hp:~# On the dockstar none of the pseudo filesystems and tmpfs showed up in the mtab. This meant that doinfg a remount on any tmpfs you would physically remount it over and have 2 tmpfs over one another. This is definitely annoying and useless I know that other distro do the link thing too but I can't recall if they also do something else along with that (like changing default mount behavior not to try write in mtab as it's a link to something that is kernel maintained). Whatever I've more urgent issues in making root readonly to be 100% ctash proof.

I soved it by creating a link just the same way you did. I don't think there are any issues with it. I am surpriesed you did not encounter this on the x86 distribution, but I was working with Slackware 11.0 at the so maybe something has changed.

I replaced /etc/mtab with a link to /proc/mounts and things seem to be ok again ... not 100% sure that it's ok to leave it this way. Anyone else spotted the same thing ? I can report that this does not happen on my x86 slackware current.
