4. After a partition on a hard disk drive is formatted with a filesystem, all partitions on that hard disk drive must use the same filesystem. True or False?
none, as fsck must be run manually for each filesystem, /, /dev/pts and /dev/shm, /, /proc and swap, all of them, as fsck is run automatically at boot for all filesystems,
