A lot of unix config files in
xx.d folders are prefixed by a number, like :
$ ls /etc/grub.d/
00_header 10_linux 30_os-prober 40_custom
05_debian_theme 20_linux_xen 30_uefi-firmware 41_custom
Is there any convention on this number? What does it mean ?
Might just be to avoid name clashing but I'm curious if there's anything more.
