No, they have a uint64 as identifier....
In mailing list some suggested to not make more than 300 snapshots in order to
avoid bad performance. But this limit is doable.
Anyway, in 32 bit mode, the inode is 32 bit too. So leaving only 24 bit for the
file inode means that you cannot have more than 24millions of files. I not sure
that this limits would be acceptable today.
