Thanks for your reply.

I put those lines in my jail startup script, substituting my own path
to the jail, but 'devfs_domount" and 'devfs_set_ruleset' seem to be
missing, and I still get the same error for the 'devfs -m ...'
command;

devfs_domount: not found
devfs_set_ruleset: not found
devfs rule: ioctl DEVFSIO_SAPPLY: Inappropriate ioctl for device

I've searched my system and can't find 'devfs_domount' or 'devfs_set_ruleset'.

Maybe you could attach a file showing what devices are created with
these commands, and i'll just write a line to delete the uneeded
devices in startup script.

This is really frustrating me :)
