This change allows detecting configuration errors during
switch-to-configuration instead of them being reported asynchronously
*after* switch-to-configuration has exited.
(And update the NixOS test accordingly.)
Due to recent changes (likely a sqlite3 update) the sqlite3 meta-command
did suddenly succeed while sqlite3 is still unable to read the still
encrypted database. It just prints the following output and doesn't
seem to try to open/read the DB (which would fail):
```
main: /home/alice/.config/Signal/sql/db.sqlite r/w
```
We can simply fix this "regression" by instructing sqlite3 to list the tables
in the database (which fails because it cannot read the encrypted DB):
```
machine: must fail: su - alice -c 'sqlite3 ~/.config/Signal/sql/db.sqlite .tables'
machine # [ 47.036720] su[1178]: Successful su for alice by root
machine # [ 47.041049] su[1178]: pam_unix(su:session): session opened for user alice(uid=1000) by (uid=0)
machine # Error: file is not a database
machine # [ 47.116070] su[1178]: pam_unix(su:session): session closed for user alice
(finished: must fail: su - alice -c 'sqlite3 ~/.config/Signal/sql/db.sqlite .tables', in 0.12 seconds)
```
Fix#181463.
Fix bug where pam_u2f options would be partially included in other pam.d
files if the module was enable for specific services, resulting in
broken configuration.
If a host key file is a symlink pointing to an as of yet non-existent
file, we don't want to remove it, but instead follow the symlink and
create the file at that location.
See https://github.com/nix-community/impermanence/issues/101 for more
information on the issue the original behavior creates.
Within a dual VM test-setup a strange behaviour was observed.
The two VMs are connected via one vde_switch instance
(instancevirtualisation.vlans = [ 1 ]; IMO a bad attribute name for
switch instances, has nothing to do with VLANs in sense of 802.1Q).
A ping on the base interface (eth1) works, but not on VLAN
subinterfaces (vlan1@eth1). A tcpdump of eth1 includes the ARP requests
tagged with the subinterfaces VLAN ID, but responses seems not to pass
the vde_switch. This works fine if performed on the base interface.
Putting the vde_switch in hub mode results in flooding
traffic to all vde_switch ports. This results in a expected behaviour
and a ping on a VLAN subinterface works as expected.
