Mount /cdrom as read-only if not using persistent files

[Daniel Richard G.]

Binary package hint: usb-creator

Wishlist item, filed against version 0.2.12 in Karmic.

If the live environment [created by usb-creator] is running off a USB drive, and is not using persistent storage, then mount /cdrom as read-only instead of read-write. This will better approximate the nature of a CD-ROM, and will additionally help guard against damage/corruption of the filesystem if it is not unmounted properly or whatever.

I should add that I've had instances where the filesystem on the USB drive does get corrupted, although I've yet to determine exactly what causes this---attempting to (un)suspend the live system on hardware that doesn't support it very well appears suspect. This is a major problem if you're traveling and a USB thumbdrive is your only means of getting a virus/malware-free Internet terminal, so I'd like the live system to treat the /cdrom filesystem with kid gloves as much as possible.

Thank you for reporting this to Ubuntu. I am marking this as Wishlist on behalf of trinikrono since this is requesting a new feature/option. I am also marking Triaged since the description is clear and should be enough for developers to work on the feature if they so choose. Please continue to let us know about any other issues that you encounter!
