I hoped it would be a re-creation of #92 (but didn't read was there so it wouldn't influence result), alas I didn't use stopwatch then & didn't note which option I used

> (#92) I didn't set up stopwatch to time correctly; but room clock said 13:16 at start of boot, and system was fully functional just as it hit 13:22

ie. system operation in ~5 mins (<5 I believe as clock had just flipped 13:22 as it appeared), but I didn't say if persistent OR live was used.

OPTION USED THIS TIME = LIVE only (not persistent)

BOOT 1: LIVE
started stopwatch as I pressed ENTER at grub
by 2 mins 43 secs the system appeared functional

BOOT2: LIVE
00:25 secs & screen blanks & messages
00:35 plymouth visible
01:11 message(s) again & plymouth gone
02:23 system fully-operational

BOOT3: LIVE
00:29 secs & screen blanks & messages
00:35 plymouth visible
01:10 message(s) again & plymouth gone
02:25 system fully-operational

BOOT4: PERSISTENCE
00:27 secs & screen blanks & messages
00:34 plymount visible
01:41 message(s) again & plymouth gone
03:06 system fully-operational

(boot 4 and there was a longer delay between wallpaper being drawn & the menu responding to wacom-pen or SUPER key being pressed & menu appearing which is what I use to detect 'fully-operational)

Boot 2 & 3 are identical; any differences will be me needing to press the screen on the phone more than once to get it to register 'lap' time.

Re-creating test #101 using Ubuntu Desktop 22.04 LTS (comment #101)

(I started time at ENTER PRESSED at GRUB, so 9 secs difference expected)

08:01 screen blanked
08:08 ubuntu plymouth first appeared
09:41 plymouth is gone, system text message(s) appear
10:08 maybe-ubiquity; TRY/INSTALL prompt
10:55 system fully operational

Times here start out consistent (9 secs difference expected as I started time with right hand as I hit enter at grub with left, last time it was when I saw 'grub' prior to grub.menu appearing), however at MAYBE-UBIQUITY times differed a bit.. and final-operational differs well beyond any user/me error(s)

Picking when a system is 'fully operational' is subjective, so a few secs difference can be just me using wacom-pen touching screen OR hitting SUPER at the right sec, versus a short delay (as I'm not hitting key/pen rapidly), but we have ~30 secs difference (10mins37secs-9sec 10m55s?)

To me as a user they feel ~stable; but BOOT 1 of Lubuntu LIVE was slower than BOOTS 2 & 3 (which were consistent; boot 4 was different mode).. and some some times of Ubuntu Desktop were identical; but by end they differed beyond I believe could be me.

They don't vary by minutes though in my opinion; secs like this is all I've generally noted (and some of those secs are likely me/dog; hitting my phone with the wacom pen for the device instead of my finger as I did on last test; I can't see that adding 20 secs though! etc)
