Subject: [PATCH] systemd: ignore lack of tty when checking whether colors
|
||
|
|
should be enabled
|
||
|
|
|
||
|
|
When started by the kernel, we are connected to the console, and we'll set TERM
|
||
|
|
properly to some value in fixup_environment(). We'll then enable or disable
|
||
|
|
colors based on the value of $SYSTEMD_COLORS and $TERM.
|
||
|
|
|
||
|
|
When reexecuting, TERM should be already set, so we can use this value.
|
||
|
|
Effectively, behaviour is the same as before affd7ed1a was reverted, but instead
|
||
|
|
of reopening the console before configuring color output, we just ignore what
|
||
|
|
stdout is connected to and decide based on the variables only.
|
||
|
|
|
||
|
|
(cherry picked from commit 158fbf7661912adf0f42c93155499119811dde82)
