I've put together a small system with busybox, a Linux kernel, and a small file system, putting stuff in as it seemed necessary -- I don't know if I've been learning much from this, but I started out pretty clueless, so it sure hasn't been a smooth ride. So I suspect I might be missing some stuff in my filesystem, but I'm really not sure what I might need to add next.

I can boot into my system by typing in the following grub commands: set root=(hd0,msdos1) \ linux /vmlinuz root=/dev/sda1 \ boot

Once the boot messages stop, I'm left with this (I'm not sure if it's related but there's a line there that says: VFS: Mounted root (ext3 filesystem) readonly on device 8:1): boot message

I can't modify the filesystem: ln: bin/mkdir Read-only file

It's funny because I can manually mount /proc just fine: mounting /proc

Why is my file system read-only? What would I need to set up to get it to work?

It's not unusual for a system to boot / readonly at first and then remount it rw later on. (I think the idea is that one would like to get to binaries like the file system check e2fsck in /sbin/ without risking breaking anything.) –  Ulrich Schwarz Feb 27 '12 at 11:33
    
maybe your filesystem is corrupt, have you tried to check it ? –  Coren Feb 27 '12 at 13:16

I don't know, why is your system read-only, try to search in dmesg | less. If you would like remount it to read-write, use mount -oremount,rw / command.
