--- Comment #8 from John Hein <jcfyecrayz@liamekaens.com> ---
Note that the linux implementation of these is random, whereas the the freebsd
linuxulator implementation is not:
for ii in 1 2 3 4 ; do cat /compat/linux/proc/sys/kernel/random/uuid ; done
d5491552-a0b6-11ec-a963-90b11c7011ef
d5495a75-a0b6-11ec-a963-90b11c7011ef
d5497ded-a0b6-11ec-a963-90b11c7011ef
d549b78d-a0b6-11ec-a963-90b11c7011ef
One might consider this a deficiency or just an idiosyncratic difference
between linux and linuxulator. But if it is a deficiency, this is a separate
bug. I only made a comment here instead of opening a bug since I'm not sure if
I would call it a bug. I guess I lean toward deficiency as the linux random(4)
page that documents these files (uuid & boot_id) says "These read-only files
contain random strings ...". Maybe it's an open question whether people in the
"real world" depend on true randomness for these values.
