More than this, one can put /usr on a stripe set so that /usr/bin and /usr/lib, two of the directories with the highest I/O traffic, can be made more performant. But this requires LVM, RAID or some blend of both. This, in turn, precludes that it be merged with /, unless the initramfs grows even more to handle those extra DASD management facilities. The more I think about this merge of / and /usr, the dumber I think the idea is. As I wrote in an earlier message on this list, the initramfs will be many times larger than the kernel itself. Indeed, my /boot partition is only 32 MiB, and that will be too small to contain all the extra libraries and programs to run the initramfs script. > > Mounting it read-only > > seems the only sensible one, and then I think is better to go all > > the way and mount / read-only. > > Putting /etc on a read-only filesystem seems a really bad idea.
