The only possible reason behind having /dev as a separate partition would be to prevent a mistake like dd if=install-disk.img of=/dev/sda (note that OpenBSD does not have the device named sda), which would create a regular file named /dev/sda, potentially several GB in size. The real solution is to be more careful when executing any commands as root, especially one such as that. Also, command line completion (Tab key) helps.

| Aug 25, 2024 at 8:44 | comment | added | Vilinkameni | /dev uses around 40kB on OpenBSD 7.5, of which ~12kB go to the MAKEDEV script, so there really is no need to have it as a separate partition. It is the directory holding just the device pseudofiles (plus the mentioned script, and a few lockfiles). | |

Because you (almost certainly) need the binaries on /usr/bin.

They don't necessarily have the same mount options. You probably want noexec on /var, or /tmp, but not on /usr or /. You might need wxallowed on /usr/local but not anywhere else, etc etc etc. Logs will not fill up / until they do, and then you'll be screwed if you can't even log in. There are plenty of reasons for using separate mount points, and, in an age where virtually any storage medium has at least 16Gb, efficiency is definitely not a problem, IMHO.
