BW64 comes with Fsearch and plocate, two fantastic file finders. Fsearch with GUI, no CLI, and plocate with CLI, but no (dedicated) GUI. Both have their pros and cons and both work basically the same: They create a database of all files of all currently mounted devices (or better:partitions).
With one exception: They don't scan the current install partition, in my case sdb1.
IMHO this is wrong and should be fixed
For Fsearch I see 2 possible solutions:
1) In Preferences/Database/Include add
/initrd/mnt
This will allow /initrd/mnt/dev_save (essentially my sdb1) and /initrd/mnt/tmpfs (which includes /initrd/mnt/tmpfs/tmp, a folder which I find useful because that's where AppImages are mounted). What is not desirable is the inclusion of /initrd/mnt/tmpfs/pup_rw, so /initrd/mnt/tmpfs/pup_rw has to be added to the Exclude list.
With /initrd generally exluded this all looks inconsistent, but it works well because settings for subfolders override settings for parent folder.
2) The second solution is easier and involves only changes in the Exclude list:
Deactivate /initrd
In the "Exclude files:" entry box add
pup_*
This will exclude folders /initrd//pup_* and also /initrd/mnt/tmpfs/pup_rw but shield any other stuff in /initrd from exclusion. Of course it would also exclude any other files or folders that start with 'pup_', e.g. folder /usr/local/pup_event or file /etc/profile.d/pup_gtk. Not ideal but maybe acceptable as a personal configuration. Less collateral damage would be possible with something more precise like
pup_[a-z];pup_r[ow]*
As for plocate things are a bit more complicated because plocate keeps no white list and does't even allow wild cards, but it's possible. If there is an interest in plocate I may explain later, but for now let's concentrate on Fsearch.
