RE: [ts-7000] TS-7250 filesystem access before and after chroot

[Jim Jackson <>]

sounds like what you really need is a boot via a suitable initrd setup so
that the whole system actually has the correct '/'

I think you misunderstand what chroot is.

chroot acts for the chroot invoked process  and its children.
You can have different sessions chrooted to different places all on the
same system.

One "fix" would be to alter /etc/inetd.conf to invoke ftpd as

 chroot /usbflash/root ftpd .....

but as I said this is stickingplaster and you'll probably have lots of it
around. Best get your board booting with the root on the correct device.
