When I was bitten by the "amd64 -current crashs at boot" problem (I did not
pay attention to the initial reports because of the subject line -- I am using
i386), both my netbsd and onetbsd kernels started failing the minute I
installed userland (including the new kernel modules). I was lucky to find an
old 5.99.4 kernel that I could use to rebuild and reinstall the ffs module. I
have now invested $20 in a USB stick that contains a working bootable 5.99.5
system and that I can use to fix any future mishaps.
