Reboot - Fix command not found, add Apline support, fix Solaris command (#49272) * Fix various bugs related in reboot - Use format strings for consistency and improve debug log messages - Use local variables instead of class attributes in order to be thread safe - Run setup module to get distribution and version - Run find module to get full path of shutdown command - Use ansible_os_family and ansible_distribution to find commands and args - Use same command for all Solaris/SunOS distributions - Move delay calculations to properties - Reliably check for module run failure - Fix bug in run_test_command() that accidentally made the method work properly - Use better exceptions rather than Exception - Use dict literals rather than constructors - Correct _check_delay() so it always returns a value, not None - Don't store and return result in run_test_command() because it's not used anywhere - add test for post reboot command that fails - test negative values for delay parameters 6 years ago			`- name: Get current boot time`
reboot - add reboot_command parameter (#69847) Fixes #51359 * Update default search paths * Fix returns for args and command, don't allow conversion * Reorganize tests * Fix test for Azure Pipelines 4 years ago			`command: "{{ _boot_time_command[ansible_facts['distribution'] \| lower] \| default('cat /proc/sys/kernel/random/boot_id') }}"`
