So, how about (using your btmp directory) create symlink to /dev/null in the (dev) sub-directory and then set no write permission? No tmp, things are local to build output, old gas's happy: ,__ |olecom@flower:/tmp/_build_2.6.19-rc3/btmp !__$ mkdir dev ,__ |olecom@flower:/tmp/_build_2.6.19-rc3/btmp !__$ cd dev ; ln -s /dev/null null ; chmod u-w . ; ls -la total 0 dr-xr-x--- 2 olecom root 60 2006-10-30 15:34 . drwxr-x--- 3 olecom root 80 2006-10-30 15:34 .. lrwxrwxrwx 1 olecom root 9 2006-10-30 15:34 null -> /dev/null ,__ |olecom@flower:/tmp/_build_2.6.19-rc3/btmp/dev !__$ cd .. ; rm dev/null rm: cannot remove dev/null': Permission denied ,__ |olecom@flower:/tmp/_build_2.6.19-rc3/btmp !__$ echo ok > dev/null ,__ |olecom@flower:/tmp/_build_2.6.19-rc3/btmp !__$
New featured dev/null may be set in some kind of make variable, say $(null) in scripts/Kbuild.include. ____ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
