Comment(by Quozl):

 Replying to [comment:3 maraschino]:
 > What is the expected delta of journal size from clean build 802 to 850?

 The Journal should not change in size very much.  The metadata format is
 slightly different, but the metadata is not a substantial fraction of the
 size of the journal data.  Available free space for the Journal to use
 will change because after an update from 8.2.1 to 10.1.2 there will be a
 copy of 8.2.1 still on the laptop.

 > Noticed that a clean 802 build on the machine produced around 524MB of
 free space.

 I've tested, and a clean 8.2.1 build (os802.img) on an XO-1 leaves 767 MB
 of free space.  I presume you are not using a clean build, but rather a
 build with activities.  Testing again with gg-802-1.img with md5sum
 33f096d4653c4199e85b61586af09476 shows free space after install of 545 MB.
 That's near enough to 524 MB assuming there may be different bad block
 counts, or perhaps you ran ''Software update''.  It is possible that in
 the 75.6 MB of downloads of changed activities are some activities that
 may grow in size, and 21 MB is not entirely out of the question for this
 growth.

 > Subsequent update to 850 left only 60MB.

 Since roughly 467 MB is required by the update, assuming 524 MB to start
 with, free space should be about 57 MB.  This is very close to the trigger
 point of 50 MB for "Journal is full".

 If it is not possible to update from gg-802-1.img with activity updates to
 10.1.2, then in the absence of a solution I shall remove that as a
 supported option.
