           Summary: systemd init system: /tmp is not mode 1777
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: bos at je-eigen-domein.nl
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


Using:

- latest buildroot from git
- start with raspberrypi2_defconfig
- set systemd as init system
- initramfs linked into kernel

/tmp is not mode 1777 causing software that does not run as root and wants to
write to /tmp or (linked folders like /var/log) to fail.

==
# ls -ld /tmp
drwxr-xr-x    7 root     root           220 Jan  1 00:00 /tmp
==

Also tmpfiles service fails to start:

==
 systemd-tmpfiles-setup.service - Create Volatile Files and Directories
   Loaded: loaded (/lib/systemd/system/systemd-tmpfiles-setup.service; static;
vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 1970-01-01 00:00:06 UTC; 2min

  Process: 131 ExecStart=/bin/systemd-tmpfiles --create --remove --boot
--exclude-prefix=/dev (code=exited, status=1/FAILURE)
 Main PID: 131 (code=exited, status=1/FAILURE)
==

And logging is not functional:

==
# journalctl
No journal files were found.

Are you sure you have not done some mistake? I just tested generating an initrd
with systemd support, and it boots fine under Qemu, and /tmp has 1777 access
rights:

drwxr-xr-x    4 root     root             0 Jul  7 21:01 var

Can you confirm that the issue is still reproducible with the latest Buildroot?

Thanks!

Issue with /tmp not being mode 1777 when systemd is used, is no longer
reproducible with recent buildroot from git.

Logging is still broken when systemd is used, but there is already bug 7892 for
that, so closing this.
