The overlayfs_qa_check checks if the current root file system has a
mount configured for each overlayfs, when the overlayfs class is used.
However there are certain instances where this mount point is created at
runtime and not static in a fstab entry or systemd mount unit.
One such case would be if overlayfs-etc is used, where the device is
mounted in the preinit script and not via a mount unit or fstab entry.
However there are other possibilities for this as well, like startup
scripts that support a dynamic partition layout. For instance when
systemd-repart is used.
This adds the `OVERLAYFS_QA_SKIP` variable, which allows to define QA
skips via its flags. In principle it supports multiple QA skip flags
separated by whitespace, but only one (`mount-configured`) is
implemented here. To skip this QA check simply add `mount-configured` to
the flag of `OVERLAYFS_QA_SKIP` with the same name. For instance if a
overlayfs is configured as:
OVERLAYFS_MOUNT_POINT[data] = "/data"
Skipping this QA check can be done by setting:
OVERLAYFS_QA_SKIP[data] = "mount-configured"
