syntactic bug in entrypoint.sh

[Fuma419]

Describe the bug Redirect the output of the sed command back into the script file itself using >>. This can lead to unintended consequences like duplicating or corrupting the file because sed -i modifies the file in place, and the >> operator appends the output of the command to the end of the file.

I did not find any functional issues. Resolving this would improve robustness though.

To Reproduce Steps to reproduce the behavior:

https://github.com/cardano-community/guild-operators/blob/5e17fc32705d84ae4529a6ea55b181f028ab9973/files/docker/node/addons/entrypoint.sh#L40

Expected behavior silence the output with '/dev/null 2>&1'
