What you are observing is typically caused by the file being replaced rather than edited. In that case, the mount-bind on the old file will remain, and you will not be able to access the new (replacement) file inside the jail. This is due to the nature of mount --bind which attaches itself to a specific inode on the filesystem rather than to a filename. There are two ways to work around this problem: 1. Actually edit instead of replace the file. 2. procd_add_jail_mount_ro a folder instead of a file. In that way, the replaced file will also show up. As in most cases only strategy 2 is truely a good option we have already moved resolv.conf.auto into a folder of its own. If the same problem also occurs for other dnsmasq config files, we shall introduce a folder for all of them and add that using procd_add_jail_mount_ro to make it accessible inside the jail instead of calling procd_add_jail_mount_ro for individual files. _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
