Personal Archlinux-LiveUSB

Hey guys,

I've got a question. Is it possible to create a _personal_ (e.g. all xorg-drivers, custom DE,...) Live-USB especially with Archlinux and modifiy it to RO (Read Only) for security purposes? If this is possible could you please explain it to me how?

Regards,

A liveCD/DVD would surely be read-only :-)

It's possible, but I've never had need to do it.
As for security, it would seem that anyone with root could simply remount the filesystem.

You might be able to do what you want with Larch.

Larch depends on deprecated AUFS2 which is no longer in the Arch kernel.

Or you could try archiso, since it is the official tool used to build Arch image releases. It's available in the AUR.

Also, give this a read: https://wiki.archlinux.org/index.php/Building_a_Live_CD

So, a "LiveCD" is better than a Live-USB? I'm asking because i'll have to travel for the next month and I need to work at Customers PC which are going to use Windows. I'll check my online banking status and my E-Mails and I thought that a LiveUSB would be the best solution for that, because it's read only. So if the stick is going to be hacked, the hacker is not able to modify it, because it's RO. That was my idea... I hope, that this is right. If not, please do not hesitate to correct me!

I'll give larch a try. Thanks for this suggestion!

What? AUFS2 is deprecated? I thought that this is the "next generation" file system of UnionFS. So, which Filesystem I'll have to use? BTRFS?

If anyone of you got a better solution, how to realize my problem, please do not hesitate to post the solution!

No it's not. Whoever says that is wrong. It's not in the Arch kernel anymore, that is true. But it's still being developed, and got a version bump, there's now aufs3. Then there's overlayfs, which is quite awesome, it's a tenth of the size of aufs3. Of course it only has a tenth of the features, but it's more than enough for a LiveUSB.
