The problem is that installing the package starts atopacct, which takes
a system-wide semaphore and then stalls. atop tries to take the same
semaphore and stalls as well.

I didn't see that in the beginning because I cannot install the build
package in a dd schroot on zelenka.

I filed this upstream, https://github.com/Atoptool/atop/issues/207
