To get system updated on Linkstation series, it's better to replace the stock firmware with system seriously maintained, like Debian.
Step0, get SSH shell access. Run on your Linux PC:
0_get-ssh/get-ssh.sh <Linkstation IP> [Linkstation web login password]
Step1, debootstrap to data partition (/dev/sda6 for one-disk version or /dev/md2 for RAID version). Run on Linkstation box:
1_debootstrap/build_rootfs_with_buffalo-kernel.sh
reboot
Step2, reboot into Debian system on data partition, then build the final rootfs on root partition. Run on Linkstation box:
/build_rootfs_with_buffalo-kernel.sh debian
reboot
After a few minutes on booting, you should be able to log into your Linkstation with Debian installed. Clean up the stuff we don't need any more:
cd /mnt
rm -rf bin boot dev dev etc home lib media mnt opt proc root sbin selinux srv sys tmp usr var run
Confirmed to be working on the model/firmware below:
- LS-VL 1.69 (Buffalo stock kernel)
- LS-WXL 1.69 (Debian Wheezy-backport / Jessie kernel + own DTB)
- LS-WSXL 1.69 (Debian Wheezy-backport / Jessie kernel + own DTB)
- LS-WVL 1.69 (Buffalo stock kernel)
