except for the act of 1) building new kernels, and 2) building src rpms there seemed to be little reason not to mount /usr read-only, so a few days ago, i did just that and have been running happily ever since. if i need to build a new kernel, i just remount RW temporarily for the duration of the build. so this has finally motivated me to move what's normally stored in /usr/src elsewhere. certainly, from what i can tell, i'm free to store and build kernel source anywhere, so i plan on moving it to my non-root home directory. also, from what i read, i can configure "rpm" and "rpmbuild" to work with a directory other than /usr/src/redhat with their config files. anyone else set things up this way? comments? potential drawbacks? something horrific i've overlooked? rday -- Robert P.
