recently openwrt trunk updated block-mount to 2013-06-20.....
then the old fstab not working any more and can't mount during boot so extroot not work.
any idea how to use it ??

1. sysupgrade: "Be aware that on rare occasions old configuration files don't work with new program versions."
2. Isn't there any up-to-date block-mount documentation? Then maybe you are going to delight us with one, after you figured out what changed ;-)

I noticed the same, but I have not had time to look for a solution, yet. Manual mounting works ok.
https://forum.openwrt.org/viewtopic.php?pid=205552#p205552
I have not seen any documentation.
Nor is there documentation about the changed button hotplug script routines :-(
I sent a question to the developer mailing list. Let's see if there is any feedback.

on the system call "block detect" to get a sample uci config.
if target is / then it will be used as extroot
"block info" is also valid to get the uuid.

"block detect" gives me this:
config 'mount'
option target '/mnt/sda1'
option uuid '8c6c-0792'
option enabled '0'By toggling enabled to '1' I can get fstab to work. But only for that one known USB stick.
How can I enable the same mount point to accept any inserted USB stick?
That was possible with the previous block-mount.
When I look at the source code, it seems to me that there is no such option...

Earlier it was possible to leave out uuid and just specify the device to be monitored.

Hello!
I'm trying to get extroot to work with ubox.
My /etc/config
config 'mount'
option target '/overlay'
option uuid '15b2386a-280c-2248-1894-7595938c1ed5'
# option options 'rw,sync'
option enabled '1'If I add any lines at all - It wont mount. like adding the options line.
and secondly - Which is the most problem for me, Overlay dont work.
It does mount work fine if mountpoint is /mnt/sda1 but then I choose /overlay it gets mounted, but the overlayfs wont update the free space left.

Well......
[option device] [option options] won't work ?
Need UUID ??
And, it won't update free space !?
That sounds terrible.....
There is now a ticket related to the new block-mount:
https://dev.openwrt.org/ticket/13774
Ok, no more block-mount,
install ubox instead.
Try compile again and try.
However, ubox is already preinstalled in my build, how come it doesn't work ??
And there is no such file /etc/init.d/fstab !??

you have to create /etc/config/fstab by yourself.
use "block detect" output as the model.
I mean /etc/init.d/fstab
not under /etc/config

The needed package is still called "block-mount" although it is provided by the ubox source.
Check it from here:
https://dev.openwrt.org/browser/trunk/package/system/ubox/Makefile#L48
http://nbd.name/gitweb.cgi?p=openwrt.gi … 03;hb=HEAD
I am not sure if /etc/init.d/fstab is needed.
I've tested mountpoint / too, both as pivot overlay and pivot root. but none works, as /overlay it gets mounted but overlayfs doesnt update free space (Sems not to work at all, dd if=/dev/mem of=/mem bs=4096 sais out of storage)
With mountpoint / it doesnt get mounted at all

This looks like a typo to me, should be "/overlay".
in additional,
[swapon -s] doesn't work anymore.
then how to check swap status ?

That was an typo, but same error even with no typo (look at my first post)

Just tried the latest trunk r37077
It can mount automatically.
However it won't mount to the designated location....
everything just mount to /mnt/sda.....
successfully pivot overlay.....
but only can auto mount with uuid.
cannot mount w/o uuid....
@johan666
Can you explain how you mount pivot overlay? Can you post your fstab? I tried lot of ways and can only mount /mnt/sda.
Thanks in advance
Just that
config global
option anon_swap '0'
option anon_mount '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '1'
config mount
option target '/overlay'
option uuid [your device's uuid, can't use /dev/sda]
option enabled 1
config swap
option uuid [I have swap partition, also use uuid]
option enabled 1Thanks johan666
I tried this and another combinations, like option delay_root '0',
option target '/' and nothing. My setup is AR7XX (TP-Link TL-WR1043N/ND v1, OpenWrt Barrier Breaker r37092 / LuCI Trunk (svn-r9844) ). Anyone with success in this setup?
