[Bug 1976630] [NEW] uuidd appears to be broken on Ubuntu 20.04 LTS

[vdbergh]

Public bug reported:

uuidgen -t returns a correct result when uuidd is _not_ running. See the
following transcript

vdbergh at pl:~/$ sudo systemctl stop uuidd.service uuidd.socket
vdbergh at pl:~/$ uuidgen -t
ef485202-e275-11ec-b7ab-448500dea459     <----  (correct: last part is the MAC address)
vdbergh at pl:~/$ sudo systemctl start uuidd.service 
vdbergh at pl:~/$ uuidgen -t
f8e7b3ca-e275-11ec-b074-1d42fae212d0   <---- (incorrect)

The same issue appears with every program that relies on libuuid.

Example: uuid.getnode() in python3 is supposed to return the MAC address
but this only works if uuidd is not running.
