Echo can interpret operand as an option and checking every variable to
be echoed is troublesome while with printf, if the format specifier is
present before the operand, printing as string can be enforced.
Make shell a little bit safer with:
- add-default-case
- check-extra-masked-returns
- check-set-e-suppressed
- quote-safe-variables
- check-unassigned-uppercase
Although there are some stylistic decisions for uniformity:
- avoid-nullary-conditions
- deprecated-which
- require-variable-braces
- Document preferred method for socket use depending on use case;
- Fix Github web-flow key;
- Standardize naming of services;
- Use sys-ssh in ansible formula;
- Start services conditionally with Qubes Service and evaluated by
systemd ConditionPathExists= instead of installing on a per qube basis
with rc.local scripts;
- Change Qusal services to "qusal-" prefix instead of "qubes-" prefix.
