[Pkg-kbd-devel] Bug#771161: kbd: setterm doesn't do its job when called from the kbd init script with systemd

Package: kbd
Version: 1.15.5-2
Severity: normal
Dear Maintainer,
As reported in bug #750631, settings such as BLANK_TIME, BLANK_DPMS
and POWERDOWN_TIME in /etc/kbd/config or /etc/kbd/config.d/* are not
being applied if systemd is the current init system.
Apparently when /etc/init.d/kbd is run under systemd, there are at
least two differences from other init systems:
- the environment variable TERM is not defined
- standard output is not /dev/tty1
For setterm to do its job, TERM needs to be known and standard output
needs to be a terminal (to which setterm wants to apply its settings).
I have worked around the issue by modifying /etc/init.d/kbd to call setterm
like this:
TERM=linux setterm > /dev/tty1 $setterm_args
as seen in the modified conffile attached to this e-mail.
On a Linux system, this apparently does what I expect it to do; even
if I explicitly state /dev/tty1, the settings are valid for all of the
virtual terminals.
I don't know whether this workaround is fit to be applied in the kbd
package, or if it should be "safeguarded" by a check for "running under
a Linux kernel" or "running under systemd", or if the right thing to do
would be something entirely different.
Kind regards,
Andreas Trottmann
