Like any other system, it is important to keep Void up-to-date. Use xbps-install(1) to update:
# xbps-install -Su
XBPS must use a separate transaction to update itself. If your update includes
xbps package, you will need to run the above command a second time to
apply the rest of the updates.
XBPS does not restart services when they are updated. This task is left to the administrator, so they can orchestrate maintenance windows, ensure reasonable backup capacity, and generally be present for service upgrades.
To find processes running different versions than are present on disk, use the
xcheckrestart tool provided by the
$ xcheckrestart 11339 /opt/google/chrome/chrome (deleted) (google-chrome)
xcheckrestart will print out the PID, path to the executable, status of the
path that was launched (almost always
deleted) and the process name.
xcheckrestart can and should be run as an unprivileged user.
If you get a kernel panic after an update, it is likely your system ran out of
/boot. Refer to "Removing old
kernels" for further information.
