targetcli service file
My service (targetcli, service file attached) needs configfs loaded before it is started, but it doesn't appear to be. I can do "systemctl start sys-kernel-config.mount" once the system is up (and then targetcli is happy) but during boot when targetcli is run, configfs isn't mounted.
Another thing -- sys-kernel-config.mount appears *almost* identical to sys-kernel-debug.mount, which IS being properly mounted. sys-kernel-config is a Before for targetcli.service and sysinit.target, but isn't being started.

The difference is that debugfs is built-in in the Fedora kernel but configfs is a module. The mountpoint does not exist until the module is loaded.
See if deleting the line "ConditionPathExists=/sys/kernel/config" from sys-kernel-config.mount helps.

That didn't have an effect, but adding /usr/lib/modules-load.d/targetcli.conf containing "configfs" did.
So I can do that, but shouldn't systemd-units really add something to modules-load.d, since it owns the unit that needs the module loaded?
(but then configfs.ko will be loaded even if sys-kernel-config.mount isn't active. Do mount units need a LoadModule or ExecMountPre option??)

I don't like userspace having to be aware of what's configured as a module and what's built-in.
One option would be to have the kernel provide the empty /sys/kernel/config mountpoint even without the module loaded (whenever CONFIG_CONFIGFS_FS=m or y).
With the mountpoint available the mount would succeed (the module providing the filesystem implementation would be loaded automatically).
Or just set CONFIG_CONFIGFS_FS=y and move on.
Kay, what do you think?

<kay> i don't think that having it as a module makes much sense
<kay> when there are non-exotic users for it
<kay> configfs was supposed to be the counterpart of sysfs
<kay> like a sysfs with commit support
<kay> so we can declare it as 'core', i guess
<kay> all that sounds like fiddling we should avoid and just compile it in
<kay> i think that was what we decided last time we changed some stuff
<kay> if it's exotic, let the package drop a force-load instruction
<kay> if it's common, let's compile it in and forget
Reassigning to kernel to consider setting CONFIG_CONFIGFS_FS=y
