Yes, but what I wanted to say was to set the ownership/permission
of the directory /var/lib/texmf as root:users/664 at the same time 
with changing those of the ls-R file.

mktexlsr includes the following:

    # Use same permissions as parent directory, minus x,s, or t bits.
    chmod `kpsestat -xst "$db_dir"` "$db_file"

so only changing the ownership/permission of /var/lib/texmf
might work?

# I still misunderstand something?

Do you mean to modify mktexlsr?
