crew files does not give size of package taking hard linked files into account.

[satmandu]

Using git as an example... (using a modified crew to hard link duplicate files in the package): total size of all files in a package:

chronos@cheekon-x86_64 /usr/local/lib/crew/packages $ ls -1is $(crew files git | head -n -2 | tail -n +2) |  awk '{print $2}' | paste -sd+ - | bc
606156

Now let's see if we ignore hard linked files:

chronos@cheekon-x86_64 /usr/local/lib/crew/packages $ ls -1is $(crew files git | head -n -2 | tail -n +2) | sort -u -n -s -k1,1 | sort -n -s -k2 | awk '{print $2}' | paste -sd+ - | bc
47896

If I don't hard link files though:

chronos@rpi4b-armv7l /usr/local/lib/crew/packages $ ls -1is $(crew files git | head -n -2 | tail -n +2) | sort -u -n -s -k1,1 | sort -n -s -k2 | awk '{print $2}' | paste -sd+ - | bc
215636
chronos@rpi4b-armv7l /usr/local/lib/crew/packages $ ls -1is $(crew files git | head -n -2 | tail -n +2) |  awk '{print $2}' | paste -sd+ - | bc

We should probably correct this as if a package can use hard linked files much space can be saved...
