Public bug reported:
When overlayroot is used with config of:
overlayroot=crypt:dev=/dev/vdc,debug=1,mkfs=1
Then the password that is used for the mount is recorded to
a file in in /run/initramfs (or /dev/.initramfs on older initramfs-tools).
The file name is currently:
overlayroot.XXXXXX
where the 'XXXXXX' is random as it is the result of
mktemp overlayroot.XXXXXX
There doesn't seem to be any value in having that filename be random.
Some things to note:
a.) file is on a tmpfs (initially created in the initramfs and then moved with
the pivot)
b.) file does (and should) have root:root permissions and 0600
It seems a general better idea to make that
/run/initramfs/overlayroot.pass
