I tried again experimental (4295238) on the same USB with the same
installation method and I get 64 seconds. I got 56 seconds with 1.1
right after that. So yes, now the increase (14%) seems reasonable.
In the previous build that ended up being super slow I also had a
MKSQUASHFS_OPTIONS = "-comp gzip" as environment variable from my
.bashrc (I removed it) :(

I confirm that on this experimental ISO isohybrid with the old versions
do not return any warning. The ISO image is 954M (in whatever unit it
returned by `ls -lh`).
