User run-time dir stopped being created at boot #46
Description
I'm not sure what changed exactly, but I found today that systemd was reporting being in a degrade state, and when I investigated further I was finding that the user@1000.service was failing to start.
Sep 14 08:36:26 atlas (systemd)[782]: pam_systemd(systemd-user:session): Failed to stat() runtime directory '/run/user/1000': No such file or directory
Sep 14 08:36:26 atlas (systemd)[782]: pam_systemd(systemd-user:session): Not setting $XDG_RUNTIME_DIR, as the directory is not in order.
Sep 14 08:36:26 atlas systemd[782]: Trying to run as user instance, but $XDG_RUNTIME_DIR is not set.
Sep 14 08:36:26 atlas systemd[1]: user@1000.service: Main process exited, code=exited, status=1/FAILURE
Digging into it futher, it appeared that the shell script called by the user-runtime-dir@1000.service (/usr/lib/bottle-imp/imp-user-runtime-dir.sh) wasn't creating the directory any more.
I've monkey patched the shell script to the below to make it work again (new line is after the # We are the WSLg user, so leave the status quo)
#!/bin/sh
if [ ! -d /mnt/wslg/runtime-dir ]
then
# WSLg is not present, so default to doing the standard thing.
/lib/systemd/systemd-user-runtime-dir $1 $2
exit
fi
# Get the UID of the WSLg runtime directory.
WSLGUID=$(stat -c "%u" /mnt/wslg/runtime-dir)
if [ "$1" = "start" ]
then
# Setting up runtime dir.
# At this point, the WSLg runtime dir will be mounted at this point anyway;
# regardless of UID.
if [ $2 -eq $WSLGUID ]
then
# We are the WSLg user, so leave the status quo.
/lib/systemd/systemd-user-runtime-dir $1 $2
exit
fi
# Otherwise, unmount the runtime dir, and then default to the standard.
/bin/umount /run/user/$2
/lib/systemd/systemd-user-runtime-dir $1 $2
exit
fi
if [ $1 = "stop" ]
then
# Unsetting up runtime dir.
if [ $2 -eq $WSLGUID ]
then
# We are the WSLg user, so leave the status quo.
exit
fi
# Otherwise, default to the standard.
/lib/systemd/systemd-user-runtime-dir $1 $2
fi
