Hello, I've been thinking about adding a feature to Busybox mount, but I'd like to check on options that are already claimed in util-linux so I don't cause a major incompatability. The feature I'm thinking about is roughly analogous to "mkdir -p" or "cpio -d": it creates the mountpoints if needed. This could be done by calling mkdir -p, or by calling mkdir() from mount. The point is to allow one to mount /dev, /sys and all their subsystems in one pass by using mount -T /etc/vfstab -a -d or something like that where /etc/vfstab contains (for example): === # Kernel filesystems to mount for bringing up the system proc /proc proc noexec,nodev,nosuid 0 0 sysfs /sys sysfs noexec,nodev,nosuid 0 0 devfs /dev devtmpfs defaults 0 0 devshm /dev/shm tmpfs nodev,nosuid 0 0 devpts /dev/pts devpts noexec,nodev,nosuid 0 0 === I'm thinking that the option should be ignored with -o bind, because that may take a file or a directory. Do you have any comments about the concept? As far as I can see, -d, -m, and -p are all available (at least in the version of util-linux mount that ships in Jessie). Are there any plans to use any of these options? Also, is there any interest in seeing this in util-linux mount? (I'd assume some of the corresponding code would be added to libmount, but I haven't really looked at util-linux code before--just Busybox and Toybox mount(8) implementations.)
