Usage: ${0} <Synology Model Name> <Options>

Options: update, postupdate, noconfig, noclean, manual, realmac, userdts

- update : Option to handle updates to the m shell.

- postupdate : Option to patch the restore loop after applying DSM 7.1.0-42661 after Update 2, no additional build required.

- noconfig: SKIP automatic detection change processing such as SN/Mac/Vid/Pid/SataPortMap of user_config.json file.

- noclean: SKIP the 💊   RedPill LKM/LOAD directory without clearing it with the Clean command. 
           However, delete the Cache directory and loader.img.

- manual: Options for manual extension processing and manual dtc processing in build action (skipping extension auto detection).

- realmac : Option to use the NIC's real mac address instead of creating a virtual one.

- userdts : Option to use the user-defined platform.dts file instead of auto-discovery mapping with dtcpatch.
