/etc/fstab: Fix. Removed "UUID=26ada0c0-1165-4098-884d-aafd2220c2c6 /               ext4    noatime,errors=remount-ro 0       1" since we are no longer using development/deprecated/1500_change-partition-uuid.
deleted whonix_shared/etc/fstab.whonix, this is now handled by whonix_shared/usr/share/whonix/postinst.d/70_create_swap_file, which is better, because Whonix doesn't have to own /etc/fstab anymore. Less prune for error and more compatible with physical isolation users.
whonixcheck, timesync: cleaner locking mechanism, no longer using pgrep, thus fixing a confusing message while booting
