I am a bit confused why my filesystem is only 4mb , how can I utilize more of it in a safe manner

/rom is a squashed filesystem of system files that generally never change. It is always 100% full and never changes without re-flashing the whole OS. The remainder of the flash space is formatted as /overlay. This is where files added or changed during runtime are stored.

when trying to install a package , I was prevented due to lack of space any idea why? I thought I would have more

What package(s) were you trying to install. You have 56MB of free space on the overlay -- that should be enough for many different packages to be installed, but it obviously depends on what it is.

opkg install crowdsec
opkg install crowdsec-firewall-bouncer

Those two are 56+ MB, it'll fill your overlay (all remaining flash space).
