Patch request - ujail

[voltagex]

I believe I was just bitten by this one:

https://git.openwrt.org/?p=project/procd.git;a=commitdiff;h=04d7570f473ca2a657a89f74ac4027f6c94f4305;hp=039b88f75367203e540009cc97603b1bce3fafa6

If you tell ujail to mount a file that exists, it gets overwritten (?)

I am not sure which upstream branch this patch is in.
