[mantic:linux-signed][PATCH 3/5] UBUNTU: Install snapd-info file if available

[Dimitri John Ledkov]

Kernel snaps require top-level snapd-info file, as extracted from the
initrd. Vendor it into the signing tarball and install it in
.deb. Note this file is likely to move soon, thus two locations are
checked.
