[Bug 898373] Re: fsck.ext3: Device or resource busy while trying to open /dev/xvda2

[Stefan Bader]

Hm weird. I would have expected at least a rw open on the block device should fail, let alone a ro (since fsck probably wants to modify the fs). Though I'd need to check exactly what access mode mount -oro uses (maybe its some ro exclusive). Actually it is not really a read-only open on the block device (that much I know) because this still will cause changes to the superblock (mount time and so on) if that is possible and the block device itself is not read-only.
Beside that you could restrict the devices touched by looking at /sys/block/?/device/type which is 5 (cdrom) only for cd type devices.
The other option would be, if there is an event that mountall emits as the final one (done with automounting), that would be a safer time to start with the cloud-init, wouldn't it?
