grml-info: fix browser selection

[zeha]

Split out of grml/grml-live#500 to deal with the browser selection.

grml-info starts a browser with some basic documentation about Grml (defaults to startpage.html)

FTR, grml-info launches different browsers:

• from grml-quickconfig (non GNU/screen terminal, with framebuffer): links2 in framebuffer mode is launched
• from grml-quickconfig (non GNU/screen terminal, framebuffer disabled): links2 in text mode is launched
• from within GNU/screen: w3m (in text mode) is launched
• from within X: links2 in X mode

We should decide whether to change the default browsers (especially within X). I'd suggest using Firefox as the default, and if it's not there, go to the lesser featured browsers.

Nice catch, thanks. Yes, let's use firefox within X. The proper solution is to use x-www-browser and then use whatever is configured for it via update-alternatives, in our grml-full case that's firefox-esr.

No idea about the console browser and what to prefer there, though consistency would probably be preferable?

Re framebuffer: links2 -driver fb no longer works:

At our on-site dev meeting we looked into this together, summary of our findings and dicussion:

• w3m by default does not display images on FB/console, but with w3m-img it actually is able to display images (though w3m-img would be an actual option only for grml-full as it depends on plenty of libraries)
• we don't ship links2 any longer (its FB is gone, see https://tracker.debian.org/news/1594540/accepted-links2-229-2-source-into-unstable/)
• we ship links, it's small and while it doesn't display images, its rendering seems to be better than w3m, esp. with default configuration and URLs (hard to read on black console with blue URLs in w3m, being much better in links)

Unless there's a good reason to change the behavior of our browser selection in grml-info (the script was moved from grml-scripts to grml-live), we can keep it as-is and nothing needs to be done about it. We ship only links with grml-small and grml-full nowadays.
