How to pass parameters to the kernel under solaris

A dynamic method for passing parameters to the kernel under solaris. The method is different from that of the solaris system. On solaris, the transfer method is to modify/etc/system, but not on linux. My system is a Ubuntu system, such as modifying the zfs kernel module... a dynamic method for passing parameters to the kernel under solaris. The method is different from that of the solaris system. On solaris, the transfer method is to modify/etc/system, but not on linux. My system is a Ubuntu system. for example, to modify parameters of the zfs kernel module, $ echo 64>/sys/module/zfs/parameters/zvol_threads can change the number of zvol threads to 64. But first, these are all in the sys File System. Therefore, you must first obtain the write permission chmod + w/sys/module/zfs/parameters/zvol_threads. The implementation method is as follows: for example, in A. c file, add unsigned long f = 0;... to the end of the file and add the following two lines. Module_param (f, ulong, 0444); MODULE_PARM_DESC (f, "the kernel module test f parameter ");
