rootflags

Synopsis

                  rootflags [option] image [flags [offset]]

System administration command. Set flags for a kernel image. If no arguments are specified, print flags for the kernel image. flags is a 2-byte integer located at offset 498 in a kernel image. Currently the only effect of flags is to mount the root filesystem in read-only mode if flags is nonzero. You may change flags by specifying the kernel image to change, the new flags, and the byte offset at which to place the new information (the default is 498). Note that rdev -R is a synonym for rootflags. If LILO is used, rootflags is not needed. flags can be set from the LILO prompt during a boot.

Option

-o offset

Same as specifying an offset as an argument.
