The image contains a copy of bpftrace pre-installed as well as tools bundled
with every release. The bpftrace binary is the pre-compiled release binary
provided by the project, via their github page. Upgrading to a new release
involves replacing /usr/bin/bpftrace with a new copy of the binary and that is
it.

Viewpoint Linux currently uses pkgsrc to provide packaged software.
There is a repo of packages alongside the bootstrap kit published at
http://files.venture37.com/pkgsrc/packages/Linux/Viewpoint/0.0/x86_64/

The packages are built from the pkgsrc-2021Q1 stable branch, bootstrapped with
--prefer-native yes to opt to use components already provided with the distro,
rather than build another copy from pkgsrc.
For changes made to pkgsrc and packages for BCC, bpftrace, systemtap, see the
viewpoint-pkgsrc repo.

All packages were built with CFLAGS="-fno-omit-framepointer -g" but there may
be packages which explicitly strip binaries by default unless instructed not
to. Those packages which support USDT probes have been built with them
enabled, such as X11, Python 3.8, Perl, Postgresql, MariaDB.

If you're struggling to think of a scenario to practice with GDB, bpftrace,
BCC, try pointing them at the various componets of the OS and drill down from
there. Though the OS comes with bpftrace preinstalled, GDB and BCC are
provided as packages via the pkgsrc repo.

Fetch and extract the bootstrap kit by pointing tnftp at
