Sorry, I hadn't been paying enough attention. If you are awaiting a
kernel upgrade, you don't have enough space in /. My current two kernel
modules directories are each around 175MB, with /lib totalling 445MB.
You can't run /lib anywhere but inside /, so I don't think you have too
much choice but to plan for a bigger /.
Until quite recently, 'a few hundred megs' was enough for /, now it
isn't. Not only have the kernel modules mushroomed, but we are now
strongly advised to merge /usr into /. The boot process is getting
cleverer, and starting to want /usr stuff mounted during boot. There
are ways to arrange to mount a separate /usr, but that's another thing
to go wrong/get forgotten, it's easier to merge it in.
