Per the Alpine Linux Wiki running LXC requires the following apk packages in addition to the lxc package:
* bridge
* lxcfs
* lxc-download
* xz
* lxc-templates
* gnupg
On our default install of Alpine 3.17 edge, who is a symlink to busybox. who seems to work with the -H flag at least enough to print headers, but who does not seem to list logged in users with the -a flag or without any flags.
The busybox who source linked below (the last of the listed references) doesn't seem to require coreutils, but maybe I missed something.
Would some kind soul please explain why who shows the headers with the -H option but doesn't show me and others besides me who may also be logged in?
Thanks!

Q: Why is the utmp/wtmp functionality only implemented as stubs?
if the feature is implemented, you need to take additional measures to protect your user’s privacy
in order to use the utmp/wtmp feature, you need a suid/sgid binary to modify the database, which opens the door for security issues:
if you compromise those binaries, you can inject arbitrary data into the db, that other programs might interpret in exploitable ways that’s a HUGE risk to pay for the sake of a basically-useless and possibly-harmful “feature”

Downtime for maintenance December 27 and 28. This is from @Cloudie.
Thanks!
Dec 27 and 28 are the day after tomorrow and the following day cuz today is the 25th. Right now be your last chance to make a backup if there is anything you want on the server.
What have I missed about LXC and GCC friends?
Anybody wanna switch off Alpine and goto NetBSD or Slackware or Gentoo or something else?
Where are all the very fun guys from NodeSeek? They seem quiet lately!

Hi Tom!
Thanks for the new password, problem solved. I can log in now. thank you very much!
Looks like you are doing some interesting stuff on the server! That's great! Do you want to share details about what's happening?

Sure! I had run a nginx server without privilege
Just run the script below,the nginx server will start up in a Udocker container !
Change the NginxPort in the script if the port number is used by someone.
cat > run_nginx_with_udocker.sh << 'EOF'
curDir=$(dirname $(readlink -f "$0"))
UdockerVersion=1.3.5
udockerHome=$curDir/pri/udocker
export UDOCKER_DIR=$udockerHome/udocker_dir
export PATH=$udockerHome:$PATH
NginxImage='nginx:1.23.1-alpine'
if [ ! $NginxPort ]; then
#change port number if already used
NginxPort=2080
fi
if [ ! -d $udockerHome ]; then
mkdir -p $curDir/pri
cd $curDir/pri
#download udocker bin
wget https://github.com/indigo-dc/udocker/releases/download/$UdockerVersion/udocker-$UdockerVersion.tar.gz
tar zxvf udocker-$UdockerVersion.tar.gz
rm udocker-$UdockerVersion.tar.gz
#instal udocker lib udockertools
udocker install
fi
# download nginx image if not exist
if ! udocker ps | grep $NginxImage > /dev/null ; then
udocker pull $NginxImage
fi
# create nginx container if not exit
if ! udocker ps | grep nginx > /dev/null ; then
udocker create --name=nginx $NginxImage 2>&1
fi
# run the nginx container
udocker run -p $NginxPort:80 nginx
EOF
bash run_nginx_with_udocker.sh
"udocker is a basic user tool to execute simple docker containers in user space without requiring root privileges. Enables download and execution of docker containers by non-privileged users in Linux systems where docker is not available. It can be used to pull and execute docker containers in Linux batch systems and interactive clusters that are managed by other entities such as grid infrastructures or externally managed batch or interactive systems.

Here are some more questions for possible consideration:
What does everyone think about giving some or all neighbors sudo?
How about installing some kind of containers or VMs, letting neighbors do whatever they want inside their container or VM, but not giving sudo on the node?
Does anyone (maybe those who get containers, VMs, and/or sudo?) want to contribute to the $30/month cost of the server?
It's okay with me just to leave things as they are for now. But I am equally happy to consider alternatives. Special thanks to @terrorgen for helping get the discussion started!
Thanks in advance for your helpful comments!
Best wishes!

No to everyone having sudo
lxc container sounds good, if that's do-able (proxmox with a single shared IP)
Maintenance December 27 and 28, 2022. That's tomorrow and the following day.
Right now might be your last chance to make a backup if there is anything you want on the server.
I set up IPv4 and IPv6 monitors at Hetrix Tools so we all can see when the pings from Hetrix receive responses and when they don't. Here are the links:
There have been rumors that our fmt machine perhaps could receive an upgrade from 32 GB to 64 GB RAM. Additional rumor penumbras suggested that certain routers might be upgraded. I'm looking forward to the results of the maintenance!

Yes to sharing the cost
Hey!
Thanks for your vote on sudo. We have quite a few IPs, please recheck the server specs in the OP. Thanks for saying yes to sharing the cost. Much appreciated!
Thanks for requesting an account! Excellent to see you posting here! Welcome!
Since we haven't seen you around LES too much, would you like to share a bit about yourself and your interests? Maybe who and where you are, your Linux experience, and what you plan to do on the server? I'm sure everyone will be interested!
the maintenance downtimes happened. As of right now I have not yet heard that the maintenance officially was completed. So maybe there might be more downtime.
Nevertheless, the server seems up and running. Network performance seems much improved, and there is a second important improvement. Have some fun trying to figure out the second improvement or take a look underneath the spoiler.
Hey, our RAM was doubled! We have 64 GB now!
Last but not least, I remounted one of the 1 TB hard drives on /mnt (but it's still not in /etc/fstab). Please feel free to write some files there, if you wish. Looks like you have write access:
drwxr-xr-x 8 root root 4096 Dec 11 17:59 mnt
