Hi List I have a query about the linux shutdown or reboot process. Please can you let me know if the below sequence is correct: When reboot command is given on the shell: 1. all user-space process is frozen (by sending some signal ?? ) 2. all file-systems are remounted as read-only - (sysrq handler does this ?? ) 3. all drivers, whose shutdown handlers have been defined, are called in the reverse order in which these drivers were initialized. I am not sure what happens after this. TIA. -- Thanks & Regards ~/asd
