Specifiers in user units don't use environment.d values #29414
Description
systemd version the issue has been seen with
254.5-1-arch
Used distribution
Arch Linux
Linux kernel version used
6.5.5-arch1-1
CPU architectures issue was seen on
x86_64
Component
systemctl
Expected behaviour you didn't see
Units started with user manager would have specifiers referring to XDG variables (%C, %E, %L, %S) expand to reflect XDG settings.
Unexpected behaviour you saw
Instead, systemd seems to have passed the XDG defaults to the unit (see attached log)
Steps to reproduce the problem
Fresh user, with
#~/.config/environment.d/00-xdg.conf
LOCALDIR=/home/test/.local
XDG_CONFIG_HOME=${LOCALDIR}/etc
XDG_CACHE_HOME=${LOCALDIR}/var/cache
XDG_STATE_HOME=${LOCALDIR}/var/state
and
#~/.config/systemd/user/check-xdg.service
[Service]
Type=oneshot
ExecStart=echo "XDG_CACHE_HOME=" %C
ExecStart=echo "XDG_CONFIG_HOME=" %E
ExecStart=echo "XDG_STATE_HOME/log=" %L
ExecStart=echo "XDG_STATE_HOME=" %S
[Install]
WantedBy=default.target
(note: for some reason, placing the unit under $XDG_CONFIG_HOME/systemd/user/ rendered it visible to systemd-analyze --user verify but not systemctl --user start, but ran out of time diagnosing this)
and
#~/check-xdg.sh
echo "XDG_CACHE_HOME=$XDG_CACHE_HOME"
echo "XDG_CONFIG_HOME=$XDG_CONFIG_HOME"
echo "XDG_STATE_HOME/log=$XDG_STATE_HOME/log"
echo "XDG_STATE_HOME=$XDG_STATE_HOME"Additional program output to the terminal or log subsystem illustrating the issue
