Thanks for info. The interesting thing is the machines are both Dell
Lattitude 5580 notebooks. Only real difference is that the one with
bigger files is an machine that has been updated over a number of
versions on a 1TB SSD drive, and the one with smaller files is a
recent clean install on a 2TB nvme drive.
So, seems strange that each file is about 100M bigger.
Found some things compression, but tried it with no difference?
cat /etc/dracut.conf.d/custom-compression.conf
compress="zstd"
rebuild and it stayed the same basic size.
Both machines originally had the directory empty?
Thanks again for reply.
