Package: pipewire-bin
Version: 1.4.2-1

although package pipewire-bin has not been forked by devuan, i am encountering
behavior contrary to documentation. i am not sure if this discrepancy is due to
the absence of systemd or some other devuan difference.

the executables /usr/bin/pipewire and /usr/bin/wireplumber do not honor/accept
pipewire ENV variables. this odd behavior is not present on my debian-13 VM.

on my devuan excalibur box, /usr/bin/pipewire and /usr/bin/wireplumber output
a bunch of error messages. these error messages are expected as i have removed
package rtkit and disabled all things bluetooth. these are the error messages:

--------------------------------------------------------------------------------

as my KDE terminals are black text/white background the above error messages are
not readable due to them being colorized. according to the pipewire man page,
the colorization and other logging behavior can be changed using env. variables.

on my debian-13 VM (qemu/kvm) i did this to test out pipewire behavior:
   systemctl --user stop pipewire pipewire.socket
   NO_COLOR=1 /usr/bin/pipewire               <-- WORKS! no colorized output
   PIPEWIRE_LOG_COLOR=false /usr/bin/pipewire <-- WORKS! no colorized output
   PIPEWIRE_LOG_LINE=false  /usr/bin/pipewire <-- WORKS! line numbers omitted

my devuan excalibur box does not behave this way. none of the three ENV vars
above (NO_COLOR=1, PIPEWIRE_LOG_COLOR=false, PIPEWIRE_LOG_LINE=false) alter
the behavior of /usr/bin/pipewire and /usr/bin/wireplumber.

maybe there is some subtle difference in the devuan runtime that influences how
pipewire behaves? or maybe this package gets built anew on devuan servers? or
maybe it is just me?

perhaps nothing can be done, but i wanted to report it nonetheless.
