rootflags linux command

rootflags

rootflags [option] image [flags [offset]]

System administration command. Sets 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 non-zero. 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.
