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 qusal.ConnectTCP in dev's Access Control as it defaults to deny
and causes confusion to users why it doesn't work by default. This is
an exception of the rule that a formula cannot document the RPC service
of another formula to avoid duplication.
- Default sys-net and sys-firewall to disposable;
- Set global and per vm preferences by starting the qubes or shutting
down them when necessary; and
- Less manual steps remaining for the user: just rename the net qube, as
it can only be done via Qubes Manager.
