I made it working in old version of Barrier Breaker (r39....) by following the instruction, given here.
Today I've upgraded my router to r40477 and could not setup extroot anymore.
What's wrong?
I noticed one things: mount command with only device name as arguments returns error "cannot find /etc/fstab". Why is it looking for /etc/fstab instead of /etc/config/fstab?
/etc/fstab is linked to /tmp/fstab, but /tmp/fstab does not exist
root@OpenWrt:~# ls /etc/fstab -l
lrwxrwxrwx 1 root root 10 Apr 14 07:34 /etc/fstab -> /tmp/fstab
root@OpenWrt:~# ls /tmp/fstab -l
ls: /tmp/fstab: No such file or directoryWhy does it not exist? Who should create it?
Could it be a reson why I'm not able to mount /dev/sda (usb) on /overlay?

Do you have /etc/.extroot-uuid?
If yes, does it state the same UUID as the device you are trying to mount as extroot?
No, I don't have /etc/.extroot-uuid.

Same here on r40004 on DIR-505, but my extroot is working...
so, gentlemen, any ideas?
Had the same problem here right now after updating to r40502.
Solution that worked for me: On your extroot USB drive (not in your router's /etc/ !), search for /etc/.extroot-uuid and delete it. Reboot, done.
I temporary mounted my usb drive to /mnt/usb. There is no .extroot-uuid in /mnt/usb/etc/ 
root@OpenWrt:~# ls /mnt/usb/etc -a
. config e2fsck.conf hotplug.d modules-boot.d passwd shadow uci-defaults
.. dropbear ethers init.d modules.d passwd- shadow-tmo26, are you using pivot overlay or pivot root?
I use pivot overlay.
How does your /etc/config/fstab look?
Exactly as it is exemplified in extroot openwrt wiki.
My fstab config:
root@OpenWrt:~# cat /etc/config/fstab
config 'global'
option anon_swap '0'
option anon_mount '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '5'
option check_fs '0'
config 'mount'
option target /overlay
option device /dev/sda
option fstype ext4
option options rw,sync
option enabled 1
option enabled_fsck 0to avoid possible questions - /dev/sda has no partition table. It is whole ext4.

One last thing comes to my mind:
Increase
option delay_root '5'to 10 (or higher)
It does not help:(
root@OpenWrt:~# cat /etc/config/fstab
config 'global'
option anon_swap '0'
option anon_mount '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '15'
option check_fs '0'
config 'mount'
option target /overlay
option device /dev/sda
option fstype ext4
option options rw,sync

option enabled_fsck 0

Some more desperate tips:
- try adding ' around the arguments, e.g. '/overlay' instead of /overlay
- try mounting by UUID or by label instead of device
- check for presence of .extroot-uuid (yes, again! Yes, on both the router's /etc and the USB drives /etc)
Questions:
- The USB drive, is it a freshly formatted one or is there some old content left over on it from previous extroot?
- Any useful information in dmesg / logread?
- adding ' around arguments didn't help
- mounting by UUID didn't help
- no .extroot-uuid files in both /etc dirictories
Answers:
- yes, it was formatted by mkfs.ext4 /dev/sda before copying all /overlay to usb by tar -C /overlay -cvf - . | tar -C /mnt/sda -xf -
- I cant find any useful information there (Im inexperienced in linux), may be you can:

I discovered that my current problem with pivot overlay is only flagged on the console, not in the syslog. For some reason the error message regarding the missing dynamic link library libblkid-tiny.so is only shown on console: pivot overlay not working on Barrier Braker trunk
Saurus, yes, I found exactly what you found in your case:

tmo26, I successfully mounted /dev/sda on /mnt/usb manually, so it looks like there are no problem with absence of partition table.
But I tried your advice anyway. Nothing changed.
Hmpf... either your problem is a really seriously big one... or a really tiny simple one. I don't know which...
You've tried everything I would do. For me it's working, for you it's not.
May someone with deeper knowledge of extroot jump in, please. Jow perhaps?
You possibly did not read Saurus's post. He found that library 'libblkid-tiny.so' cannot be loaded.
He went to failsafe mode and issued "export LD_LIBRARY_PATH=/tmp/overlay/lib". Then mounted root by "mount_root". Extroot started working in pivote overlay mode! I've got the same results.
So, now the question is why libblkid-tiny.so' cannot be loaded?
Probably will be fixed in r40526.
Wait for build...

Excellent 
It's working!
It's fixed in r40526
The discussion might have continued from here.
