Hi, I saw MS_SLAVE used in the source code of systemd, but I couldn't find information about it in the manpage for mount(2). The mount(1) manpage does point to `Documentation/filesystems/sharedsubtree.txt` which describes it (although doesn't explicitly mention MS_SLAVE). After a bit of digging, it seems that MS_SLAVE is one of four related flags which also include MS_SLAVE, MS_PRIVATE, and MS_UNBINDABLE which are also missing. Manpage version is 3.35 according to the colophon. On Ubuntu Precise. Online versions seem to be missing a description for this flag as well.
