Cannot use this action twice in same job

failed to attach volume vol-123 to instance i-123 : operation error EC2: AttachVolume, https response error StatusCode: 400, RequestID: 2A6E4FB7-44E4-4AAC-A61C-6070BD043D02, api error InvalidParameterValue: Invalid value '/dev/sdf' for unixDevice. Attachment point /dev/sdf is already in use

Hey, seems like the issue is that /dev/sdf hardcoded at the moment.

Just curious, what's the reason that you need multiple volumes for a single job?

i wanted to cache both
/var/lib/docker and ~/.m2/repository (for maven packages)
using runs-on/cache for ~/.m2/repository now

Thanks for the bug report. I'm actually unsure if I want to make a single action support multiple folders, or keep 1 action = 1 folder.

If multiple folders then we can parallelize the work, but it's a bit more complex (and can't easily specify volume settings individually with the current inputs). I'm tempted to go with the 1 action = multiple folders support but what do you think?
