Change subject: core: Kernel cmdline - data layer ...................................................................... core: Kernel cmdline - data layer This feature allows to customize kernel commandline (bootloader configuration) of hosts. The configuration is stored in vds_static table in columns: kernel_cmdline and last_stored_kernel_cmdline. 'kernel_cmdline' column is JSON structured and holds values of checkboxes for UI and generated line to be send to hosts. The line is never parsed to checkboxes again. 'last_stored_kernel_cmdline' column contains last successfully stored line in host. Line from 'kernel_cmdline' column will be copied to last_stored_kernel_cmdline after successful host deploy. VdsStaticDao#update method and underlying stored procedure don't update 'last_stored_kernel_cmdline' column to prevent accidental change. There is separate VdsStaticDao#updateLastStoredKernelCmdline that called that will only be called from host deploy. Host deploy procedure will send both current and last stored line to the host because the tool manipulating bootloader configuration - grubby - can't actually read the configuration, only write. Thus old configuration is necessary to know what to remove before applying new configuration.
