Simple question about Pacman...

I'm not having any problem at all at the moment, I'm just curious about something.

Pacman has an -r option. You can use it to change the installation root of a program. I want to know if I can install extra software onto a Live CD by mounting the disk image and just using

sudo pacman -r /tmp/iso -S someapplication

Then I could dismount the image, burn it to a CD, and run that application off that live CD. I would try this if I were only sure it would work. Don't want to wast a disk, you know? No problem here. No urgency. I just would like to know...

Yes or no? Am I missing something, or shall I proceed?

More or less, but the system alone isn't enough, you also need a bootloader on the medium, so I recomment reading up on live-cds / boot media in general, and/or then try making a bootable ISO image, and first testing it in some virtualization software before burning.

Re: Simple question about Pacman...

So what you're asking is how do you create your own personalized LiveCD.

What, google wasn't much help?

https://wiki.archlinux.org/index.php/Building_a_Live_CD

There are rewritable CD's on the market, you know... But come on, use a USB stick, ffs. They're dirt cheap now. Personally I haven't burned a CD or DVD for about 5 years now, ever since I bought a 500 GB external HDD. To be honest, I don't see why you'd want to run something from a CD anyway. Because it's Read-Only? It's also slow as a giraffe turd on a highway. You can load an entire ISO into RAM (link) and then pull out the USB stick. There. Now it doesn't even have access to it anymore. Problem solved.

I bet you still use floppy disks, don't you?

Only on my Power PC

Entire post is duly noted, I should be testing ideas in virtualbox instead of foruming for answers. Also, that's many other fun things for me to play with, so twice thank you!
