Hidden Volume to work with crypttab and grub at boot on linux

[Swaiguy]

Following the tutorial www.reddit.com/r/VeraCrypt/comments/nagkru/hidden_linux_os_setup_layout_1_1_volume_lvm seems to be unsuccessful lately (For the note: Used this on a root file system btrfs, no decoy os or anything like that. Just trying to mount a hidden volume as root is all im doing.). Just requesting support to be able to mount a root encrypted hidden volume on boot in some manner as there appears to be no way as of doing this right now.

Otherwise, All else works as is. Thankyou
