OMG. git-annex-standalone.tar.gz JUST WORKS IN TERMUX
I knew I was onto something with https://joeyh.name/blog/entry/completely_linux_distribution-independent_packaging/
@joeyh it does indeed, but you can't open the webapp due to the magic url it uses for authentication
@joeyh in an unrelated matter, you might want to make it easier to write to the extsdcard using git annex. Currently you need to use a file manager to make the required directory, would be nice to not need that and need to cd there yourself.
(sadly I wouldn't use this much, because my main git-annex repo uses characters not allowed in the PoS that is FAT32)
