Comment 14 for bug 48517

So by "not supporting" you mean you will purposely leave bombs which might destroy the filesystem?

Fine, disable swapfiles, or issue big ugly warnings that it will destroy your system if you activate one under ubuntu, but if you aren't going to do that, this should be a higher priority.

It isn't not obvious that creating a swapfile risks damaging your system, but that is what the condition is.

I have four bootable partitions (Win/DOS/Mac/Linux) and I can't create a 5th due to DOS limitations. So for me it is a swapfile or NO swap. I have plenty of memory so don't need to use one but it is nice for the exceptional case.
