+++ This bug was initially created as a clone of Bug #767432 +++ Created attachment 546497 [details] 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. Please advise. --- Additional comment from mschmidt on 2011-12-13 17:46:15 PST --- 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. --- Additional comment from agrover on 2011-12-13 20:17:26 PST --- 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??) --- Additional comment from mschmidt on 2011-12-14 04:45:44 PST --- 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? --- Additional comment from mschmidt on 2011-12-14 05:06:16 PST --- <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 --- Additional comment from davej on 2011-12-14 17:19:14 PST --- done. will be in next build. (3.2.0-0.rc5.git2.3)
Please update f16 kernel too.
also done. will be in 3.1.5-5 and higher
