Convert ext3 boot filesystem to ext4
I use dropbox on linode as an easy way to deploy code / monitor logs from my laptop. I received a notification that starting in November only ext4 filesystems will be supported on linux. Grumble! The service has been useful and I'd like to continue using it.
I found this howto.

I looks pretty straightforward. My question is on step 3. Does my linode use grub? How can I tell?
Step 3: Re-installing GRUB
If you convert your boot file-system ("/boot") to ext4, and you use the GRUB boot loader, you will need to install a version of GRUB which understands ext4. Your system may boot OK the first time, but when your kernel is upgraded, it will become un-bootable.

You're only using GRUB to boot that you'd have control over if you're using Direct Disk Boot; if you're using "GRUB" as your configuration profile "kernel," that is provided by Linode, and understands ext4 already. But unless you're running a really ancient distro (think Ubuntu 8.10 or older), even if you are using Direct Disk Boot, the version of GRUB installed is going to be new enough to understand ext4.
