A Linux administrator says remounting sysfs read-write fixed inconsistent NFS readahead in containers sharing a network namespace. The reported snag is that a read-only first mount can leave later mounts unable to update device information.
Why it mattersThe author’s proposed command is mount -o remount,rw /sys, which they say clears the read-only flag. That is a specific fix for the described setup, not a general instruction to change sysfs permissions on any machine.
Discuss: Would you use a fix like this in production after testing the conditions, or should changing sysfs mount permissions be off the table without a more formal safety review?
