FYI, Under a quite "fast" system, fc-cache -f takes 13 seconds with 155 fonts.

So if a Linux installer has to run that command one by one every time
a font is being installed, it will be a huge time.

Ref:
[root@ ~]# time fc-cache -f

real    0m13.280s
user    0m8.751s
sys     0m0.486s
[root@ ~]# fc-list | wc -l
155

[root@ ~]# cat /proc/cpuinfo  | grep model | grep name
model name      : Intel(R) Xeon(TM) CPU 3.20GHz
model name      : Intel(R) Xeon(TM) CPU 3.20GHz
[root@ ~]# cat /proc/cpuinfo  | grep processor | wc -l
2
[root@ ~]# cat /proc/meminfo  | grep MemTotal
MemTotal:      1034616 kB
