I've tried searching the forum but to my surprise did not find anyone mentioning it. In the process of expanding my optfs partition, I found that that there was an extra unused space beyond the last (swap) partition. 63 MiB to be precise. Moving the swap seems like a lot of hassle so I just created a fourth partition to claim that space. But now I am not sure how to use it. Ideas I have considered so far:

1. Extend the swap partition. I don't think I really need it. I have never hit a situation when I would fill the 768 MiB I already have. Plus experience shows that switching swap off even temporarily is asking for trouble. So I would have to do it by connecting to a PC which kinda breaks my preferred way of doing everything on-device.

2. Move swap 63 MiB up and extent optfs accordingly (or even move both swap and optfs and extend MyDocs). Same drawbacks as above.

3. Use it for something like /var. Trouble is, my /var takes only about 1.3 MiB. Seems like a waste to reserve 63 MiB for it.

4. Link/mount a random directory there. But which one? I do not want to suddenly run out of space or have to change my setup every time I install or uninstall an application. Another disadvantage is that it won't be backed up by BackupMenu. So it should ideally be something more-or-less static.

5. Any other ideas?
