The initial ramdisk on the default SD card was not developed for the
TS-7400, as the TS-7400 doesn't use TS-SDBOOT by default. The TS-7400 is
shipped with TS-FLASHBOOT. It is not required nor recommended to change
your bootrom on the TS-7400. One can still use the filesystem on the SD
card as their root filesystem with out modifying the bootrom. This is
what the linuxrc-sdboot script is for. If you don't want to drop to the
fastboot environment then you should delete the fastboot file.
e.g. Taken from TS-7400 Manual, Getting Started
Should you wish to automatically bypass the fastboot and proceed
directly into starting the SD card version of Linux, you can do
so
with the following command issued to the fastboot shell:
ln -sf /linuxrc-sdroot /linuxrc; save
For the onboard flash the command is:
ln -sf /linuxrc-mtdroot /linuxrc; save
For the USB flash dongle or USB hard drive:
ln -sf /linuxrc-usbroot /linuxrc; save
To get back to the fastboot shell, you can do so by placing the
file
"/fastboot" in the root directory of the filesystem.
As a result of several customers installing TS-SDBOOT on TS-7400s we
provided the new SD card driver and linuxrc script as an example of what
needs to be modified in the default linuxrc scripts in order to boot a
TS-7400. Once you change that example linuxrc script(e.g. ln -sf
/linuxrc-sdroot /linuxrc), then you're board will no longer boot as you
have found.

Based on the ln command you ran I would expect linuxrc to be a symbolic
link to linuxrc-sdboot. Hopefully the info above explains why this won't
work on a TS-7400 with TS-SDBOOT as the bootrom.
The simplest and recommended way to use the filesystem on the SD card as
the root filesystem is to create a symbolic link from linuxrc to
linuxrc-sdboot. You do not need to modify your bootrom, this means you
also don't need to modify the contents of the linuxrc script nor do you
need to install a new SD driver. If you are dropping to the fastboot
prompt and you do not want to have to type exit, then ensure you have no
fastboot file installed on the filesystem.
