Hello I am trying to use systemd on archlinux to mount a file system on demand. Here is what Ihave done and here are my results.
Creating a ramdisk image. # dd if=/dev/zero of=testyfs.raw bs=4096 count=1000 # mkfs.ext4 -F testyfs.raw Making a mount point in /mnt # mkdir /mnt/testyfs Adding an etnry /etc/fstab with automount systemd params. # cat /etc/fstab | grep testyfs /root/testyfs.raw /mnt/testyfs ext4 rw,relatime,data=ordered,noauto,x-systemd.automount 0 2 Trying to get systemd to see the new change # ls /run/systemd/generator | grep testy <nothing> # systemctl daemon-reload # systemctl restart mnt-testyfs Failed to issue method call: Unit mnt-testyfs.service failed to load: No such file or directory. [root@t61p generator]# # ls /run/systemd/generator | grep testy mnt-testyfs.automount mnt-testyfs.mount # mount | grep testyfs <nothing> So far this looks good # ls /mnt/testyfs/ <nothing, hmm, I thought it would automount the file system since I was referring to the directory?> Reboot to see if mounts the file system After reboot, ls /mnt/testyfs # ls /mnt/testyfs lost+found Yes, its mounted, but was it mounted at boot or because I requested it? Based upon the time in journalctl it looks like it was mounted on boot. I'm confused. I thought the systemd automount capability was supposed to mount on demand. It appears it does not mount on demand but instead mounts on boot. Have I reconfigured something or do I misunderstand what automount means? -- John F.
