Just today I found that rust-coreutils makes installing cuda toolkit impossible, related to use of `dd`: https://forums.developer.nvidia.com/t/cuda-runfile-wont-extr...
Do you have more details? The thread you linked was about gzip, not dd.
The .run file is a shell script with a compressed archive appended:
MS_dd "$0" $offset $s | eval "gzip -cd" | UnTAR t
MS_dd()
{
blocks=`expr $3 / 1024`
bytes=`expr $3 % 1024`
dd if="$1" ibs=$2 skip=1 obs=1024 conv=sync 2> /dev/null | \
{ test $blocks -gt 0 && dd ibs=1024 obs=1024 count=$blocks ; \
test $bytes -gt 0 && dd ibs=1 obs=1024 count=$bytes ; } 2> /dev/null
}
