Hi,
On my "new" Bullseye machines the root volume starts to fill up. The cause
seems to be the /usr/lib folder.
On my older Buster (10.13) machine the total /usr directory is 701M, the
/usr/lib folder is 260M
In my /usr/lib folder on Buster is NO /usr/lib/modules folder
On my Bullseye machines the /usr/lib folder is 2+GB on the machines that have
been operating for a while and 1+G on a machine that has been operating for a
shorter while.
The cause seems to be the folder /usr/lib/modules#

Guessing on what I see these are libraries for older kernel versions. I usually
clean up older kernel versions by using
# apt autoremove"
All 3 servers have 1 older kernel version installed according to apt autoremove.
Why is this stuff there? Can I delete it?
If I can delete it, is there a proper way to clean it up or do I just rm
/usr/lib/modules/5.10.0-.... for the older kernels?
Is this a BUG in Bullseye?
p.s. Looking at this I just noticed I need to do an update on lunutr, I will
dis that right after sending this mail ;-)
