try:
mount -o remount,rw /
which remounts a mounted filesystem as read-write.
you can also mount -o remount,ro / which will remount it read-only, but it
will produce a 'filesystem busy' error if any process holds an open write
handle on a file.at the time.
changes disappearing sounds like you're in a tmpfs or ramfs, which is
characteristic of initrd/initramfs which usually only exist early in the
boot process. If it's anything like the ts7800 I played with recently, you
have to quit the initial shell to proceed to booting from the sd card.
As for your man problem, try mounting a tmpfs over /tmp like this:
mount -t tmpfs tmpfs /tmp
and try again. If it still doesn't work, have a play with strace if it's
available.
