This is required so that the mount options of these file systems \(em which are pre\-mounted by the kernel, the initrd, container environments or system manager code \(em are updated to those configured in /etc/fstab and the other sources\&. This service ignores normal file systems and only changes the root file system (i\&.e\&. /), /usr/, and the virtual kernel API file systems such as /proc/, /sys/ or /dev/\&. This service executes no operation if no configuration is found (/etc/fstab does not exist or lists no entries for the mentioned file systems, or the partition table does not contain relevant entries)\&. .PP For a longer discussion of kernel API file systems see \m[blue]\fBAPI File Systems\fR\m[]\&\s-2\u[1]\d\s+2\&. .PP Note: systemd\-remount\-fs\&.service is usually pulled in by \fBsystemd-fstab-generator\fR(8), hence it is also affected by the kernel command line option \fIfstab=\fR, which may be used to disable the generator\&. It may also pulled in by \fBsystemd-gpt-auto-generator\fR(8), which is affected by \fIsystemd\&.gpt_auto\fR and other options\&. .SH "SEE ALSO" .PP \fBsystemd\fR(1), \fBfstab\fR(5), \fBmount\fR(8), \fBsystemd-fstab-generator\fR(8), \fBsystemd-gpt-auto-generator\fR(8) .SH "NOTES" .IP " 1." 4 API File Systems .RS 4 \%https://systemd.io/API_FILE_SYSTEMS .RE
