Ubuntu 24.04: no network by default

[sebalix]

Problem

While /etc is shared with the sandbox, on Ubuntu 24.04 using systemd the /etc/resolv.conf is a symlink to /run/systemd/resolve/stub-resolv.conf, which is not bind mounted in the sandbox resulting with no network access.

Proposed solution

I added this config entry to make it work:

# Network access
EXTRA_RO_BINDS+=( "/run/systemd/resolve" )

Alternatives considered

Should it be added dynamically by ai-bwrap as soon as $SHARE_NET is true and /run/systemd/resolve exists on the host?

Great wrapper BTW! Thank you.
