updatedb refuses to run at all on a config that defines a variable twice
("variable `PRUNEPATHS' was already defined"), so any rewrite that misses
an existing line and appends a second one takes the locate index down
rather than fixing it. Two shapes updatedb accepts got missed: a trailing
comment after the value, and a setting indented by whitespace.
Read the existing paths out of the quoted value and write the whole
setting back canonically instead of splicing into a line of unknown
shape. Quotes are not optional to updatedb ("value in quotes expected
after `='"), so a bare value is already a broken config: rewriting it
quoted repairs the file as a side effect.
The tests now hand every rewritten file to the real parser through
`updatedb --config-file`, which is what caught this.
Read the Snapper config as root when the running user cannot read it.
snapper create-config leaves the config root-only, and a config the user
cannot read was passing for one that wants its timeline snapshots kept.
Report the snapshots the drain could not delete. omarchy-migrate writes
the completion marker whether or not the batches succeeded, so there is
no later run to pick up the remainder, whatever the comment claimed.
