When calculation of swap file offset is unsupported, rely on the
/sys/power/resume & /sys/power/resume_offset values if configured
rather than requiring a matching swap entry to be identified.
Refactor to use dev_t for comparison of resume= device instead of string.
In the steps given in #13850, the resulting graph looks like:
C (Anchor) -> B -> A
Since B is inactive, it will be flagged as redundant and removed from
the transaction, causing A to get garbage collected. The proposed fix is
to not mark nodes as redundant if doing so causes a relevant node to be
garbage collected.
Fixes#13850
The Synaptics Touchpad that comes with the T490 doesn't explicitly set
its resolution, so these lines are needed to provide that, in order to
help the libinput code detect overly large jumps. Since this device
contains buttons under the lower section of the touchpad, large jumps
are common, so having the resolution helps libinput greatly reduce
the number of occurances of pointer jump.
This comes from
https://gitlab.freedesktop.org/libinput/libinput/issues/402.
When processing list of units (either provided manually or as a
wildcard), let's skip units for which we don't have an on-disk
counterpart, but note the -ENOENT error code and propagate it back to
the user.
Fixes: #14082
This avoids nasty race conditions between dnf/apt-get and unfinished
population of /tmp (among other things), as `docker exec` allows commands
to run before the system is fully booted (i.e. initializing/starting
state reported by `systemctl is-system-running`).
This has been requested many times before. Let's add it finally.
GPT auto-discovery for /var is a bit more complex than for other
partition types: the other partitions can to some degree be shared
between multiple OS installations on the same disk (think: swap, /home,
/srv). However, /var is inherently something bound to an installation,
i.e. specific to its identity, or actually *is* its identity, and hence
something that cannot be shared.
To deal with this this new code is particularly careful when it comes to
/var: it will not mount things blindly, but insist that the UUID of the
partition matches a hashed version of the machine-id of the
installation, so that each installation has a very specific /var
associated with it, and would never use any other. (We actually use
HMAC-SHA256 on the GPT partition type for /var, keyed by the machine-id,
since machine-id is something we want to keep somewhat private).
Setting the right UUID for installations takes extra care. To make
things a bit simpler to set up, we avoid this safety check for nspawn
and RootImage= in unit files, under the assumption that such container
and service images unlikely will have multiple installations on them.
The check is hence only required when booting full machines, i.e. in
in systemd-gpt-auto-generator.
To help with putting together images for full machines, PR #14368
introduces a repartition tool that can automatically fill in correctly
calculated UUIDs on first boot if images have the var partition UUID
initialized to all zeroes. With that in place systems can be put
together in a way that on first boot the machine ID is determined and
the partition table automatically adjusted to have the /var partition
with the right UUID.
