Linode only supports ext4 (some services will break if not using ex4)

[ghost]

I understand that the linode marketing team has been hard at work to hide the fact, that many linode services only support ext4 and there is no warning about this on the linode website.

But, I believe you should be honest about it within the linode Manager.

There should be warnings in various places to inform people of a potentially serious problem, for example:

• BACKUPS: What if someone installs a system with BTRFS (Fedora distro) or XFS (CentOS distro) and enables backups? Then one day discovers that backups only work with ext4?
• NETWORK HELPER: Someone will be wondering why his custom image doesn't receive an IP address on boot. Only to discover that the network helper only works with ext4?
• DISC RESIZE: How about when someone decides to resize their drive? OOppss that only works with ext4.
• ...etc..

May I remind everyone what a surprise it is for those of us who install a linode with MongoDB, only to discover that we have to wipe everything and start over, because MongoDB hates ext4 and will complain severely about it, for performance reasons. But if we switch to XFS we loose backups.

What I am trying to say, in my humble opinion, there should be ample warnings that linode services require ext4 and the implications of using an alternative file system.

Thank you.

PS:
This is not a feature request to support more file systems, I understand that the whole linode infrastructure is based on ext4 for some reason and that can't be easy to change. This issue is about informing the user about this severe limitation.
