wrong initramfs is created/updated by dkms

[yhaenggi]

After building and installing spl/zfs for an older kernel, the scripts run update-initramfs -u without specifying the kernel, which results in the current running kernel's initramfs being updated. spl dosnt run update-iniramfs so it only affects zfs. Having just 1 kernel with zfs support seems wrong too, but thats another issue.

ie, it should be

update-initramfs -u -k 3.13.0-76-lowlatency

how i've build the modules:

sudo dkms build -m spl -v 0.6.5.4 -k 3.13.0-76-lowlatency && sudo dkms install -m spl -v 0.6.5.4  -k 3.13.0-76-lowlatency
sudo dkms build -m zfs -v 0.6.5.4 -k 3.13.0-76-lowlatency && sudo dkms install -m zfs -v 0.6.5.4  -k 3.13.0-76-lowlatency

Output:
