I have a laptop running Ubuntu Core, which hasn’t been booted for a few weeks. I booted it today, expecting some snap updates. Sure enough, as soon as it boots up the snaps start refreshing. A core update triggered a reboot. When the system came back online, another update triggered a reboot soon after.
Why don’t we batch those operations, rather than have multiple restarts in succession?
popey@localhost:~$ snap version
snap 2.35.4
snapd 2.35.4
series 16
kernel 4.4.0-138-generic
Note the restart at 10:27 (core update) and then again at 10:32 (kernel update)
popey@localhost:~$ last reboot
