From 40a5df71e7af5feefacae9fc95bf94e72c6c12f4 Mon Sep 17 00:00:00 2001 From: Andreas Rammhold Date: Fri, 2 Nov 2018 21:15:42 +0100 Subject: [PATCH 12/19] inherit systemd environment when calling generators. Systemd generators need access to the environment configured in stage-2-init.sh since it schedules fsck and mkfs executions based on being able to find an appropriate binary for the target filesystem. With this commit I am altering the systemd behaviour since upstream tries to gather environments with that they call "environment-generators" and then seems to pass that on to all the other executables that are being called from managers. --- src/core/manager.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/src/core/manager.c b/src/core/manager.c index e23d47b4a4..1047aadebc 100644 --- a/src/core/manager.c +++ b/src/core/manager.c @@ -4145,10 +4145,15 @@ static int manager_run_generators(Manager *m) { argv[4] = NULL; RUN_WITH_UMASK(0022) - (void) execute_directories((const char* const*) paths, DEFAULT_TIMEOUT_USEC, NULL, NULL, - (char**) argv, m->transient_environment, - EXEC_DIR_PARALLEL | EXEC_DIR_IGNORE_ERRORS | EXEC_DIR_SET_SYSTEMD_EXEC_PID); - + (void) execute_directories((const char* const*) paths, DEFAULT_TIMEOUT_USEC, + // On NixOS we must propagate PATH to generators so they are + // able to find binaries such as `fsck.${fstype}` and + // `mkfs.${fstype}`.
