Wildcard Support for Fault Injection Configuration

[Natnael-Getachew-Yirga]

I'm using LazyFS for fault injection, but I need to target files where the names aren’t known in advance. It would be great if I could use a wildcard (e.g., *.txt) in the configuration instead of specifying exact file names. Right now, trying to add faults after files are created hasn’t worked.

Example Configuration

Current setup:

[[injection]]
type="torn-op"
file="output1.txt"
occurrence=5
parts=3 # or parts_bytes=[4096,3600,1260]
persist=[1,3]

What I would like to use:

[[injection]]
type="torn-op"
file="*.txt"
occurrence=5
parts=3 # or parts_bytes=[4096,3600,1260]
persist=[1,3]

Feature Request

Please add wildcard support (like *)for the file field to make fault injection work with dynamic file names.

Expected Behavior

• Applying fault rules to any file that matches a wildcard (e.g., *.txt).

If there’s a workaround I may have missed, I would greatly appreciate your guidance. Thank you for your time and consideration!
