25 I went to 3.16.6 instead.

40 since I don't update that often specifying a certain version is... not
41 really necessary.

43 And updating a kernel means a reboot. Since rebooting has a high chance
44 of something going wrong (too many times I saw a hdd or ssd that worked
45 fine moments ago die on reboot), and disrupts whatever I am doing (all
46 those nice konsole tabs) and costs times (s3 to desktop is just so much
47 faster). I spend a lot of time with a certain kernel.
48
49 For depclean - I can't even remember the last time I run it.

54 as others have written already: ssd.
55
56 With a caveat: if an ssd dies, it will die suddenly. Without a warning.
57 Usually 5 minutes before the start of your weekly or monthly backup run.
58 And that is first hand experience.
