True. And, I see a typo in my post -- that should be 500 MB.
The question is why their initrd files are 5 times as big as normal. unicorn:~$ ls -l /boot/initrd.img-* -rw-r--r-- 1 root root 30924690 Jan 29 2021 /boot/initrd.img-4.19.0-13-amd64 -rw-r--r-- 1 root root 34310935 Jul 21 07:30 /boot/initrd.img-5.10.0-7-amd64 -rw-r--r-- 1 root root 34313404 Jul 31 09:05 /boot/initrd.img-5.10.0-8-amd64
Agreed. "153M" and "151M" are considerably larger than expected: 2021-08-01 13:45:08 dpchrist@dipsy ~ $ cat /etc/debian_version ; uname -a 10.10Linux dipsy 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux

We get these threads too damned often. Someone who knows what makes initrd images swell up, please step in and advise. And no, it's not "try using a different compression algorithm". It's something in the *content*. The only advice I can give is "open them up and see what's inside them, and compare that to what you see in a regular Debian stable initrd file". But that's a lot of work, and I can't imagine an Ubuntu user actually doing that.[1] Unfortunately, it may turn out that what makes them 5 times as big is something unique to Ubuntu. Perhaps they ship a hundred megabytes of extra non-free firmware. Who the hell knows? Not a Debian list, that's for sure. [1] But just in case I'm dead wrong, here's the contents of mine, to compare against. Attached, compressed. It's a large text file, but it compresses pretty well. Maybe the list software won't strip it.
I don't know why the OP's initrd files are large.
