Yeah just let me buy my coffee while travelling... waiting for confirmation... sorry still waiting. Shit, I missed my flight (who don't accept cryptocurrency)
Those Linux systems that aren't getting updates must be the ones sending Mirai to my Linux systems, which are getting updates (and also Mirai, although it won't run because it's the wrong architecture).
No malware? Only if you have your head in the sand.
I assume that comment was saying that they handle the update process and that their machines don't have any malware on them.
I ignored it because it was somewhat abusive and is missing the problem that automatic updates are trying to solve: that most people, but not all, don't do updates.
Official documentation from who? For which audience? For which use case?
Making a bootable image for what kind of system? My Ryzen PC needs a very different image to my aarch64 router.
Where have you not seen info on "installing a bootloader to a target disk"? This is what every distro installer does - this can range from putting a kernel in an EFI partition and setting a variable to building a uboot image and setting variables in NVRAM
Lastly, what do you class as a "decent installer process"? Things have moved on from Slackware's installer. You've got everything from the Debian installer (which hasn't changed much) to Anaconda (let's run the install UI in a browser) to Ubuntu Server (everything is a container!) and many things in between.
