Colin Walters 12cc4e5f5b composepost: Fix race condition in timestamp checking 
`syncfs()` isn't going to do anything on e.g. `tmpfs` and even
if it did wouldn't fix any race conditions because that's about
synchronizing in memory changes to disk, but won't change
what system calls return.

Some investigation turned up
https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond
and `current_fs_time` is now:
https://www.kernel.org/doc/html/v5.12/core-api/timekeeping.html

Basically there's a "coarse" time that might only update once every 10ms
for example.

Let's just sleep 100ms for now.

I think we should be using the inode versions, but we can investigate
that separately.

rpm-ostree: A true hybrid image/package system

rpm-ostree is a hybrid image/package system. It combines libostree as a base image format, and accepts RPM on both the client and server side, sharing code with the dnf project; specifically libdnf. and thus bringing many of the benefits of both together.

Features:

  • Transactional, background image-based (versioned/checksummed) upgrades
  • OS rollback without affecting user data (/usr but not /etc, /var) via libostree
  • Client-side package layering (and overrides)
  • Easily make your own: rpm-ostree compose tree and CoreOS Assembler
