Investigate swap files instead of swap partitions

[ikeydoherty]

Ubuntu is going to now default to swapfiles on new installs. Potentially quite a good idea, so we should investigate the exact details and consider implementing this in Solus via the installer

Pinged @xnox to query whether to use sparse or allocate the regions beforehand

note formatting is odd in the description, w.r.t. urls syntax.

• swapfiles are not supported on btrfs
• fallocate can allocate a file quickly, suitable for swapfile, on some filesystems (creates file with holes on xfs, works like a charm on ext4)
• for encrypted use case, using ext4 fs encryption is to be investigated yet

We had Bountysource running once, just to see "was it worth it". Never went anywhere. I disabled the plugins everywhere, removed Bountysource's access.. and this is the net result. Every so often it vomits over our issues.. :)

Cheers for responding here, somewhat unexpected :D
