Lockdown and disable drives fix

EasyOS has the capability of booting up running totally in RAM with the drives disabled. There are actually two types; not actually disabled, just all unmounted, and secondly truly disabled. There is an introductory webpage:

"Ultra-secure web browsing"

Alfons reported a problem with lockdown, that turned out to not be a problem; however, while testing lockdown I noticed something else -- the "save" icon was missing from the desktop. The original "update" icon was there, but it was supposed to be replaced by a "save" icon.

Booting up in lockdown mode, there is an information window, and the "save" icon should be there, like this:

Testing on my Lenovo Ideacentre which has 32GB RAM. That free space of 45.3GB is due to running in /dev/zram0 in RAM, which has a compressed ext2 filesystem.

I fixed it, so the "save" icon is back:

Hmmm, this bug has been there since usr-merge was implemented in Easy. I wonder how many people tried EasyOS lockdown mode, it didn't work properly and they just moved on, without reporting it. Or maybe lockdown mode hasn't attracted any attention.

Changing the subject, when there is a change of kernel, some files in /usr/lib/modules get left behind. Just a tidyup, removing them:
