Hi David,

The feature of "tail packing", that you need, is brought to perfection
in Reiser4 file system. Other file systems either don't provide tight
packing of records in the storage tree, or they are read-only. You just
need to manually patch (*) the kernel and install a pair of user-space
packages (**).

The latest stuff (against Linux-5.7) is stable. For older kernels you
will need a backport for some fixups (***). We can prepare it for you.

Reiser4 is fully supported. If any problems (including partition
check/repair) - send a message to reiserfs-devel mailing list.
