Once you have a working system, there are things you might want to do.
Page poisoning and SLUB debug
By default, Void enables slub_debug=P page_poison=1. These are hardening options and have little effect on modern hardware, but on old PowerPC Macs, the performance hit may be significant.
Therefore, you might want to remove these from /etc/default/grub and then run update-grub.
Updates
You will definitely want to update your system, especially if the live media is old. Void is a rolling distribution and therefore updates frequently. Run:
# xbps-install -Su
NTP (time syncing)
You might want to enable a time syncing daemon. This is especially important if your hardware can’t keep clock. For example, you can do:
# xbps-install -S openntpd
# ln -s /etc/sv/ntpd /var/service/
There are other NTP daemons to choose from as well.
Keep in mind that openntpd by default uses the https constraint feature. That means that unless your time is set to a correct value in the first place, the daemon will fail to set the date/time. Either use date to manually set a close enough date/time, or remove/comment out the constraints from line in /etc/ntpd.conf.
Logging
By default, Void comes with no logging daemon. There are different implementations available, socklog is simplistic and easy to use:
# xbps-install -S socklog-void
# ln -s /etc/sv/socklog-unix /var/service/
# ln -s /etc/sv/nanoklogd /var/service/
PopCorn
If you feel like helping us take over usage statistics in https://popcorn.voidlinux.org, install and enable PopCorn:
# xbps-install PopCorn
# ln -s /etc/sv/popcorn /var/service/
Other things
The official handbook at https://docs.voidlinux.org should come in handy.
