    I read the man page, but I didn’t see the answer to your question in there.

    I am assuming that it would only dump the root filesystem in your example. Other mounted filesystems like /home or /media, if they’re separate filesystems, probably aren’t included. You’d have to run a separate dump for each one.

    Best option to find out is to try it and see what happens. No better way to learn than by doing.




  • It’s not that it’s deleted automatically. If you define deleting as “not being referenced by the file system,” then it’s deleted as soon as it’s unlinked.

    Fun story - create a big file, and hold it open in an application. Unlink the file. Then compare the output of du and df for the mount point the file was on. It will differ until the app closes and the inode of the file is finally freed.
