What happened?

There appears to be a shell logic bug in IMG/cpio/ventoy/hook/debian/porteus-hook.sh.

In this block:

grep ... | awk ... | while read vtline; do
# ...
vtFindFlag=1
done

vtFindFlag is modified inside a pipeline loop (subshell in busybox ash), then checked outside the loop. So vtFindFlag remains 0 outside, and the fallback branch runs even when files were already found/patched.

Expected behavior: vtFindFlag should reflect whether any match was found before deciding to run fallback logic.

Suggested fix ideas (I can create a PR):

• Avoid pipeline subshell for the loop (e.g. iterate over temp file/list)

Relevant file:

• IMG/cpio/ventoy/hook/debian/porteus-hook.sh

Thank you!
