Guys/Gals, One of my embedded machines died a while back after several years of service (enough to erase my memory.). I am trying to rebuild the flash file system on the machine, and ran into a snag. I'm attempting to manually install 4.11-REL on this system, as it is a rather old device with little RAM (32MB), and a troublesome ACPI system. (By manually, I mean I'm creating/copying file systems from a "host" drive running 4.11 rather than use the installer)
The flash memory is only 32MB, so I have to fairly particular about what I put on it. Right now, I just have the kernel, /bin, /sbin, /etc, /boot, and place holders for /usr. I symlink in /modules, /root, /home, /var, /tmp, etc from /usr (which is an IBM micro drive). I mount /dev from another slice on the flash memory. The rule is, anything that doesn't need to be written, or is required for boot, is placed on a read-only flash slice, /dev (which doesn't actually harm the flash, but must be mounted read-write, is mounted from a separate slice on the flash, and everything else is mounted on /usr. The problem I'm seeing is that the kernel boots to "mounting root from ad0s1a" and then it hangs. I suspect that is because I don't have the right /dev entries on the primary slice's /dev. The question is what are the minimal set of /dev devices required to boot sufficiently to the point where it can attempt to mount the rest of the file systems? I know this can be done, because the original install did it this way (though it took quite a bit of hacking to get it to work right) I just lost half the secret sauce formula. The other half was remembering to create a 1MB slice, and using "newfs -b 4096 -i 128" on the /dev file system so there are enough inodes.
