I'm not sure why you think the -R flag is some sort of "ruin my data"
request. Maybe because all of this stuff is so scantily documented in
the manpage?
-R Instruct fsck_ffs to restart itself if it encounters certain
errors that warrant another run.
Who knows what "certain errors" means?
Looking at the code, it appears -R has no effect if you're in preen
mode. Hmmm, what's "preen mode" again? Don't bother looking in the
man page, you'll just find a bunch of mentions of the word preen that
say "see the -p flag" and then, surrealistically, when you look at the
-p flag it says "Preen file systems (see above)". Of course, what was
above was all the places that told you to see -p.
So, I guess I'll just keep using fsck_y_enable=YES and relying on the
fact that by default that now includes the -R option.
