but how come binaries are not found when i have the full path for the
commands...?
the install binary is only used to set the umask of the result. without it, a
simple invokation of tar also fails, even without --gzip.
i dug a bit deeper, and it turned out that the SYSTEM call i thought was coming
from guile was rebound by shepherd to point to its own SPAWN-SHELL-COMMAND.
through various complex code paths, it ends up calling fork+exec-command.
SPAWN-SHELL-COMMAND's role is to make the SYSTEM call non-blocking.
as a quick test, i have added a simple (system "ls -l /bin/sh") call to my
action, and that fails, too.
i'll need to add proper logging to shepherd and see what's going wrong. but for
that i need https://issues.guix.gnu.org/61750 merged.
