I used to manage some rack-mount servers for a garage startup. That meant dealing with:
- power (including UPS and remote power strips)
- network (LAN, router, ISP, DNS)
- server hardware
- server BIOS (i.e. pls reboot after power failure)
- OS and software updates
- user admin
- backups
And living 500 miles away from the server room taught me how many things can go wrong when I'm away, and what it takes to even monitor that. Can't easily conclude it wasn't worth, since these were multi-purpose and the equivalent capacity on EC2 would've cost a ton, but doing all that just for Xcode builds would've been silly.
Closer to the topic, I also used to just manage a remote Mac mini server. It was also not automatic. Even had both disks in my RAID1 set fail over time.
Been hosting bare metal with them for ages and it has been very pleasant.
So you should be able to just `pacman -Syu`
Yes, because XCode famously never crashes.
