Subject: [PATCH] core/swap: only make configured units part of swap.target
|
|
|
|
We used to make all .swap units either RequiredBy=swap.target or
|
|
WantedBy=swap.target. But swap.target should be the "configured swap
|
|
units", either through /etc/fstab or non-generated .swap units. It
|
|
is surprising when systemd starts treating a swap device that was
|
|
possibly temporarily enabled as a hard dependency for other units.
|
|
So do not add dependencies with swap.target for units gleaned from
|
|
/proc/swaps.
|
|
|
|
Similarly, we added dependencies for all aliases of the device name,
|
|
which clutters up the dependency graph but does not seem to bring any
|
|
value, since the status of those following units is consistent with
|
|
the main one anyway.
|
|
|
|
This should be a fix for [1], and it seems the right thing to do
|
|
anyway.
