Hello:
However, I don't see any help in an admin/user creating this file; I don't see the syntax of this file documented anywhere. I found an eight year old post on askubuntu but I think that may have been out of date.
I succeeded (I think) in creating a file system mkfs.s3ql without making an authinfo2 file, hoping that process might create the file with correct syntax, but it seems to not have.
If you could please provide the syntax I should use to create my authinfo2 file for an s3-compatible storage backend I would appreciate that.
If I'm totally wrong here, I apologise in advance, but I suggest adding sample authinfo2 files for all supported backends to the documentation. I can note, I installed the s3ql Ubuntu 18_04 package and it installs some folders in /usr/share/doc but mostly those folders are empty -- certainly no additional information is available by installing the package.
I look forward to using your software. Thank you!
