Subject: [PATCH] sysusers: add fsync for passwd (#24324)
|
|
|
|
https://github.com/systemd/systemd/pull/6636 added `fsync()` when
|
|
temporary shadow, group, and gshadow files are created, but it was
|
|
not added for passwd. As far as I can tell, this seems to have been
|
|
an oversight. I'm seeing real world issues where a blank /etc/passwd
|
|
file is being created if a machine loses power early in the boot process.
