I run the Devuan ASCII system on LVM on LUKS.
In function do_stop in file /lib/cryptsetup/cryptdisks.functions there is a vary off of the VGs
missing. So the function handle_crypttab_line_stop gives unwanted return values and sleep $i
within the funtion do_stop increments slowly to 16...
Which slows down the shutdown by unnecessary minutes.

I wrote the following patch according to the function activate_vg from /usr/share/initramfs-tools/scripts/local-top/cryptroot
which varys on the VGs before chroot.

The above patch silently varys off the VGs and makes handle_crypttab_line_stop work.

Kind regards
