What do you want different about it?
I think I have stumbled onto a similar situation that does not

So I am saying Try moving jffs2 and sqfsh before switch_root, not only
/tmp.
You may need to change their mount-points. For example,
# mkdir /jffs2 /sqfsh /tmp
# mount ... /tmp
# mount ... /jffs2
# mount ... /sqfsh
# mount
Vasanth Ragavendran:
I was doing something similar only before. it was like this
mount ... /tmp
mount ... /tmp/jffs2
mount ... /tmp/sqfsh
mount ... /aufs
mount -o move /tmp /aufs/tmp
switch_root
and now even though it wouldn't make any difference i tried even ur
suggestion
mount ...

the version of aufs is aufs2.1 since

u mean in the aufs filesystem do a mount -o move? but the folder jffs2 and
sqfsh doesn't exist. right?
You already have at least one mount -o move in your script, right?
I mean moving jffs2 and sqfsh too before switch_root.
Do you mean the last aufs2.1-31? Don't you
Vasanth Ragavendran:
I don't set the brs as I don't have the CONFIG_AUFS_SYSAUFS paramater.
Where did you see CONFIG_AUFS_SYSAUFS?
If I remember correctly, it was gone before aufs2.0 (ie. aufs1).
If your fs/aufs/Kconfig contains such symbols, I'd strongly recommend
you to check your aufs source

cross compiler. however aufs2-util packages fail to compile. it fails in
compiling the makefile of the aufs2-util. the error being
./ver: ./ver: cannot execute binary file
The reason being the file is not getting generated by
mips-linux-uclibc-gcc -I./libau -O -Wall

It might work, however the plink.c which contains a O_CLOEXEC defined in

O_CLOEXEC differs from architecture to architecture (i'm not too sure of
this though)

Hello Vasanth,
Vasanth Ragavendran:
system. however doing a mount under this new aufs filesystem still contains
the old mount values.
rootfs on / type rootfs (rw)
tmpfs on /tmp type tmpfs (rw,relatime)
/dev/mtdblock2 on /tmp/jffs2 type jffs2 (rw,relatime)
/dev/loop0 on /tmp/sqfsh type

No I was talking about the /proc/mounts only. I don't have the /etc/mtab

for umount.aufs) and i'm space constrained. But
