OpenBSD 7.5 errata 002, April 11, 2024:

Install media for alpha architecture was broken due to strip(1) bug.

Apply by doing:
    signify -Vep /etc/signify/openbsd-75-base.pub -x 002_miniroot.patch.sig \
        -m - | (cd /usr/src && patch -p0)

And then follow the instructions in release(8) to rebuild installation
media.
