Subject: [PATCH] mount: don't propagate errors from mount_setup_unit() further
ff2b41
 up
ff2b41
ff2b41
If we can't process a specific line in /proc/self/mountinfo we should
ff2b41
log about it (which we do), but this should not affect other lines, nor
ff2b41
further processing of mount units. Let's keep these failures local.

Resolves: #1809159
