From: Gustavo Zacarias Date: Thu, 27 Nov 2014 22:41:49 +0000 (-0300) Subject: skeleton: make /run a proper directory/filesystem X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d380dde1d2878bd8f09317081960bfc82b0f420b;p=buildroot.git skeleton: make /run a proper directory/filesystem Making /var/run and /run symlinks to /tmp is bad since the underlying tmpfs filesystem is mode 1777 which leads to possible security attack vectors via badly owned/mask-mode pidfiles and state files residing there. So make /run a proper directory with /var/run symlinked to it. Eventually all startup scripts and state info should be pointed to /run directly as per the linux fhs and good practice. Add a tmpfs filesystem entry for /run so that busybox inittab, systemv inittab and systemd automount mounts it there to avoid breaking the system. While at it fix inconsistent spacing in /etc/fstab by using tabs and drop the "static file system information" header whatever that means.
