Notes

sbeattie

the issue being addressed here loosens the restrictions on remounting /, to match prior allowed behavior. The only potential security impact is if, as part of the boot process, an adjustment of / attributes was expected to occur that didn’t, enabling an unexpected operation to be able to occur.
