Hi There,
Im looking for some advice on a way to install some software on my offline Rpi.
I had the thought - don't Linux CD installers run out of RAM and install packages onto a non-running system? (ie the just formatted hard drive)
So I was thinking about taking the SD card out of the Pi, to another linux machine on the internet, (x86, but I would have to use the Rpi repositories) and can you use apt-get (or another package manager) to unpack Rpi packages into the attached Rpi linux file system rather than the running system?
Is that possible? how do Linux installers do it? Whenever I search on it, it's too generic so comes up with how to install packages on the system you are running, rather than into another linux filesystem.
I have looked at apt-offline, but that seems to be updating a whole system, and I was looking for more granularity about installing just a few new packages. (and different packages for each Pi I have)
Any ideas would be helpful.
Thanks
J.

Its called chroot (change root).

You need to edit /etc/ld.so.preload in the image and comment out the one and only line with a #.

Re: Installing software into a non-running system
no, the system is definitely running. it just booted of the cd instead of the HDjds5 wrote:don't Linux CD installers run out of RAM and install packages onto a non-running system
The new root is mounted in a temporary location and built.jds5 wrote:how do Linux installers do it?
The package manager is told to use an alternate root path and it updates (the running) OS onto the HD

I mean what you are asking is possible but compared to plugging in a wifi dongle its just not even worth considering it.
Back in the old days machines without NICs were updated manually (download packages, plug into computer, update - ^&^$ need packageabc123 too, download more packages, plug into computer, repeat rinse wash).
You don't want to go back there.
