Linux系统/run/systemd空间不足问题解决
搞了olvps家原128m小内存的小小鸡，安装环境时出错了，/run/systemd空间不足
Failed to reload daemon: Refusing to reload, not enough space available on /run/systemd. Currently, 10.5M are free, but a safety buffer of 16.0M is enforced.
用df -h看看，确实不足
root@AC-GIA:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 73M 0 73M 0% /dev
tmpfs 12M 880K 11M 8% /run
/dev/vda1 2.9G 1.5G 1.4G 52% /
tmpfs 85M 0 85M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 85M 0 85M 0% /sys/fs/cgroup
tmpfs 17M 0 17M 0% /run/user/0
提示/run/systemd空间不足，那就给这个目录增加空间，就增加一行配置，vim /etc/fstab：
tmpfs /run tmpfs nosuid,noexec,size=24M,nr_inodes=4096 0 0
