If the page is marked as dirty, it will eventually be flushed to disk. Pages are below the FS layer, so whether the FS is read only or read write won't matter at all if the page is marked as dirty. Not to mention the fact that the OS could very well think it was writing to a different filesystem but, due to memory corruption, ends up overwriting bits of the read-only filesystem. -- Alexandre Oliva http://www.ic.unicamp.br/~oliva/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org}
