Hi! As mentioned on IRC, running a daemon from a guix relocatable pack on a foreign distro using the user namespace feature is troublesome: it looks as if the daemon "loses" (its view of) the file-system once the parent process that creates the daemon exits.
I'm attatching a package description for a test package "vork". It builds a program "test" that forks the program "daemon". The daemon program reads a character from /dev/urandom, prints it, and sleeps for a second; 10 times. The "test" parent program exits after 5 seconds. When the parent program exits, the daemon crashes. To reproduce, put "vork.scm" in a fresh directory and do something like: --8<---------------cut here---------------start------------->8--- fakeroot tar xf $(GUIX_PACKAGE_PATH=. guix pack --relocatable\ --symlink=/gnu/bin=bin guile shepherd vork --no-offload) guix gc -D $(guix build -f vork.scm) touch /tmp/daemon.log tail -f /tmp/daemon.log & GUILE_LOAD_COMPILED_PATH=$PWD/$(ls -1d gnu/store/*profile)/lib/guile/3.0/ccache\ :$PWD/$(ls -1d gnu/store/*profile)/lib/guile/3.0/site-ccache gnu/bin/test --8<---------------cut here---------------end--------------->8--- this gives something like --8<---------------cut here---------------start------------->8--- .daemon-start daemon: 10 ? .daemon: 9 ? .daemon: 8 T .daemon: 7 ^O .daemon: 6 O exit 20:42:38 janneke@dundal:~/src/guix/master/vork [env] $ 20:42:38 janneke@dundal:~/src/guix/master/vork [env] $ Backtrace: Exception thrown while printing backtrace: In procedure public-lookup: Module named (system repl debug) does not exist --8<---------------cut here---------------end--------------->8--- Greetings, Janneke
