Hello!
I am Debian maintainer of `runit' supervision suite. Recently, I received bug report [^1] about stray .u logfiles. After some investigation I found code, that caused issue, but it seems that it was written with some purpose, yet I fail to understand that purpose. Author Gerrit Pape directed me here. Any clarification would be welcome! Please keep bug in thread. [^1] https://bugs.debian.org/916230
