Dom0 may not sent /etc/yum.conf but only /etc/dnf/dnf.conf - handle this
case too. Since dom0 use dnf for a long time, prefer dnf.conf.
Not all versions of dnf supports cachedir option, so handle also the
case when it's set by default to /var/cache/dnf (instead of overriden
with /var/cache/yum with yum.conf). Simply look for packages in whole
/var/cache.

parted tries to load random data for possible partiont table UUID
generation, even though there is no need to generate new UUID. In case
of early VM startup, this is very undesirable as random entropy pool may
not be initialized yet, which will cause parted to block.
Use sfdisk instead, which doesn't try to do that. And also can relocate
backup GPT and resize partition in one go.

The previous approach used `df` to get usable space and then added a
fixed size to that number in order to account for filesystem
overhead. However, at some point that stopped working for me. It
appears that ext4 filesystem overhead can vary over time or because of
other factors. (Certainly now that I think about it the old code would
only work well for people with the exact same filesystem size as me.)
So the new approach is to just completely ignore what `df` tells us
and instead go directly to the source: the filesystem's internal
notion of exactly how much space it takes up. We use `dumpe2fs` to
retrieve this information and calculate the on-disk size dynamically
from that. Then we add the space that boot data takes up (unchanged),
and we add 5MB padding because when I tested this it didn't quite add
up otherwise. https://unix.stackexchange.com/a/13551/29146 suggests
that this unaccounted-for data may be e.g. additional copies of the
superblock.
Network setup scripts, especially for network backend use 'ip' tool, so
the iproute package should be installed for this to work.

It is needed by the startup scripts to create fs on fresh private image.
Otherwise /rw (and thus /home) isn't mounted and user applications fail
to start.

for details; but tl;dr:
* Journal size is 64M
* Inode table is 256 bytes * 643376 inodes allocated = ~157M
* Reserved GDT blocks take up 1024 blocks * 4096 byte block size = 4M
* Fixed-size parts of the filesystem probably take up another MB or
two
These actually adds up to more than the 222M number used in this
commit. But it seems _about_ right, so just Ship It(tm).
This reverts commit 8000e76d43, because
as @marmarek pointed out, the original was correct and I totally
misread. The check in question is checking whether to _abort_, not
whether to continue. So we want to check if the block device size is
_less_ than the filesystem + margin, not more.

qubes-core-agent depends on -qrexec, there is no need for the opposite
dependency. In fact one of the reasons for the package split was to
allow installing just -qrexec package.
Base qubes-core-agent package have common files used by various
subpackages. It is important to update them at the same time, otherwise
for example python stubs in /usr/bin/* (like qubes-firewall) will not
match actual python modules.
