Exclude list does not match when using snapshot feature

[blueyed]

When using bup-cron's snapshot feature (-s LVM), bup index gets called like this (via bup-cron -s LVM /):

bup index --exclude-rx-from=/etc/backup-exclude-bup.txt --one-file-system /media/bup/vg0-rootlv

The exclude list however has paths relative to / tailored to / and therefore don't match the mounted location (/media/bup/vg0-rootlv).

how would you expect this to be fixed? should we rewrite the exclude file?

[blueyed]

I'm not sure. Probably some new option for bup would be required to adjust the root prefix for excludes? Something like the --graft option from bup-save, but for bup-index?

Rewriting the excludes might be too fragile, although it might be as easy as replacing ^\^ with \^${new_prefix}.

it would be the solution yeah, but it seems pretty hackish.
