* libmount: revert X-* and x-* meaningKarel Zak2016-12-091-9/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's hope this is last change necessary to cleanup x-* usage: x-* persistent option, stored in utab, available for umount, etc. X-* fstab comment only mount(8) supports x-mount.mkdir= as well as newly recommended X-mount.mkdir= Advantages: * less invasive * does not require exception for x-systemd * does not require rename x-initrd to X-initrd The systemd and dracut users will get the new (=fixed) functionality without a change in fstab configuration. This is the primary goal. Disadvantages: * not 100% compatible libmount behavior, x-* options have not been previously stored in utab. The API is the same, options will be still available, but on x-* libmount will write to /run/mount/utab. For now it seems only systemd uses x-*, and they like this behavior, so...

* libmount: use x-systemd options as X-*Karel Zak2016-12-081-0/+7
| | | | | | | | | | | | | | | | The previous patch introduces X-* options namespace for options that have to be maintained in user space. Unfortunately, systemd users already use mount options that are necessary by umount or another operations. The conclusion from discussion with systemd guys is to store all the systemd options in userspace. It seems better to add one line exception to libmount than force all fstab users to rename x-systemd to X-systemd.

* libmount: introduce X-* commentsKarel Zak2016-12-081-1/+3
| | | | | | | | | | | | | x-* are fstab only and not stored in userspace (utab). In some cases it's not optional solution because the option is also necessary for umount or another operations. The X-* is exactly the same as x-*, but stored to utab (or mtab on old systems). It's usually bad idea to store mount options in userspace, but it's better to provide any solution that force users to bypass mount(8) (and friends) and implement 3rd-party incompatible solutions.

* libmount: allow to use propagation flags in fstabKarel Zak2013-01-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel does not allow to change more than one propagation flag by one mount(2) syscall. The flags also cannot be mixed with another mount options. It means that the propagation flags cannot be stored in /etc/fstab, manual "mount --make-* <mountpoint>" is always necessary after successful mount. Painful... This patch implements additional mount(2) after previous successful mount(2) (or exec /sbin/mount.<type>). For example: mount /dev/sda1 /A -o private,unbindable,ro or fstab entry: /dev/sda1 /A auto ro,private,unbindable is implemented by three mount(2) calls: - 1st mounts /dev/sda1 with MS_RDONLY - 2nd sets MS_PRIVATE flag - 3rd sets MS_UNBINDABLE flag. It's the same as as to manually call: mount /dev/sda1 /A -o ro mount --make-private /A mount --make-unbindable /A This solution is not atomic, and umount(2) is not called if propagation flags are not successfully applied, only error is returned. This change does not affect libmount API, so one beautiful day when mount(2) syscall will be improved we can drop this nasty patch. Signed-off-by: Karel Zak <kzak@redhat.com>
* mount: distinguish between MS_COMMENT flags (netdev, nofail, ...)Karel Zak2012-02-231-0/+4
| | | | | | | | | | Since util-linux 2.12h (year 2004) there is only one flag for all dummy options like _netdev or nofail. Unfortunately it means that when mount(8) composes the final mount options string for mtab (or for mount.<type> helpers) the string is generated incorrectly.
