128 GB SD

I have found conflicting information on whether or not any model pi can support 128 GB SD cards. From what I can determine, Raspberry Pi requires the boot volume to be formatted FAT or FAT32, both of which should be possible with a 128 GB card (either formatting the whole thing FAT32 or having a FAT...

Autorun script after mount

I need to auto run a script after fstab is processed, but before LightDM is started. It appears that my scripts in rc.local are being executed after LightDM. To be more specific, in fstab I'm creating tmpfs directories, and I need to populate those directories immediately after they are created, so ...

Access original /actual folder

On the SD card partition used by the pi I have a path /home/. In my fstab I define a tmpfs in place of /home/. What I want to know is can I still directly access the physical /home/ folder on the SD card partition, so I can copy the contents into the tmpfs version that is now at /home/ at startup. T...

Re: How to make Raspbian read only?

Regarding the desktop not starting up with a read-only filesystem: lightdm-gtk-greeter is trying to write to the file /var/lib/lightdm/.Xauthority
I just added /var/lib/lightdm/ as another tempfs type entry in fstab and it is now launching.

Looking for case with enclosed SD

I posted this back in March and am asking again as I'm sure more cases are on the market now. I'm looking for an enclosure in which the SD card is totally enclosed. I don't care whether or not the SD card can be easily accessed (IE whether there is an access door or if you have to remove screws to g...

Re: Looking for case with SD enclosed

i was thinking of getting one of these but then i thought with the usb power socket sticking out the same side, what's the point? or are people using some sort of flat micro usb cable or something? No, it's just to "consumerize" the device so the SD card isn't pulled out while it's running, and to ...

Looking for case with SD enclosed

I'm looking for a pi case that does not have the SD card jutting out the side. So obviously the case would have to be larger than "normal" to enclose the entire SD card, but that is fine. Some kind of door to snap open to slide the SD card out would be good. Has anyone seen an enclosure like this? I...

Re: Netflix via HTML5 only

This is still a better potential solution than Silverlight in every way. Having one small binary blob that is lean and mean and is just a decoder is far better than having to run in an entire virtual machine and set of libraries (controlled by Microsoft no less). This route would be more memory and ...

Re: Readonly rootfs

To answer a couple of my questions, yes that modification to /etc/fstab does mount rootfs as read only. And yes, it can be remounted as writable in order to make changes if necessary: sudo mount -n -o remount,rw / However, neither Openbox nor Apache are starting up with the read-only filesystem. So ...

Readonly rootfs

What is the best way to mount root as readonly? Will everything (openbox, etc) even function with a RO filesystem? It seems I can modify /etc/fstab and add the ro flag to / and that should do it. However, can I then remount root manually to make it writable if necessary, or am I then stuck and the o...

Re: Wikipedia offline viewers

The HTML is hardcoded into the server code. kiwix-serve.cpp, line 624 is what needs to be changed to do away with the javascript button code. I don't have a build environment set up and don't have the time to do that right now.

Re: Wikipedia offline viewers

Yeah, you're right, it's a javascript issue. The HTML generated is using javascript to load pages when buttons are clicked, but that is totally unnecessary. A fix would be to wrap each button in a FORM with method="GET" and the action="URL-TO-LOAD". So instead of buttons like: <button id="kiwixhome"...

Thanks, I grabbed the precompiled binaries and am going to give the HTTP server a try. Just out of curiosity, why are the binaries so large? 28 MB each is pretty huge unless they contain embedded resources of some kind.
