On first VM's boot, setup-rwdev.sh script create filesystem on
/dev/xvdb. But it does so only after checking if /dev/xvdb is really
empty, by comparing it to /dev/zero. Speed up reads from /dev/zero bu
using larger blocks (default of head - 8k, instead of explicit 512).
This speed up the check over 5 times.

Drop fakeroot for list/search actions on Debian
dom0-update: add some approximation of 'list', 'search' and 'reinstall'
dom0-updates: refactor for ease adding new actions with old yum
Previously the script was called through shell as:
execl(shell, "-sh", "-c", "/usr/lib/qubes/qubes-rpc-multiplexer
...", 0);
This tells the shell to load login scripts, including /etc/profile.
Since 5512e4eada this is no longer the
case and the script is called directly. Since most services do expect
proper user session initialized (/etc/profile loaded etc), adjust the
script's shebang to behave like a login shell and load those startup
scripts.

This avoids duplicating service call parsing in multiple places.
Further improvements to that code (like avoid using shell) can be
implemented in one place.
... instead of requested user. This makes sure that session startup
script will be able to send a signal here to notify about session
startup.
This is especially needed when the first service started in the VM is
called as root (like qubes.InstallUpdatesGUI).

Update dom0 about all applications installed, not only desktop files for
them. Update also supported features and other things advertised
initially at template installation.

When VM is set to synchronize the time with the network, to not sync its
time with clockvm.
Besides not having sense, in default configuration it will lead to
loopback qrexec connection (sys-net -> sys-net), which will hang.

NetworkManager reports a bunch of events, reloading DNS at each of them
doesn't make sense and is harmful - systemd have ratelimit on service
restart.

nullglob must be active before a glob is used on a potentially empty
directory. Call shopt immediately after the shebang line.

Call it just after creating base chains in iptables/nftables. This allow
the user to modify how those rules are plugged in, add custom rules at
beginning/end etc.

The most common thing to fix S3 sleep is to unload PCI devices drivers
before suspend. Instead of having every user figuring out what drivers
needs to be blacklisted, detach all drivers from actual PCI devices.
Exclude qemu emulated devices.

qvm-run-vm cannot make a separate qubes.WaitForSession call for a
DispVM. Instead, pass the new WaitForSession argument to qubes.VMShell,
which will do the equivalent.
GNOME automatically set scaling factor to 2 when HiDPI is detected.
Unfortunately it does it also on not really HiDPI displays, making the
whole UI unusably large. There is no middle ground - scaling factor must
be integer, so 1.5 is not supported. Lets opt on a conservative side and
fallback to scaling factor 1.
