I've downloaded a Linux distribution and tried it on my PC. When I checked the documentation I noticed that there was no information about how it was developed. I wonder if it was developed using Gentoo so I did a
grep -ir 'Gentoo' /
and found these matches:
/lib64/modules/3.18.140/kernel/drivers/media/dvb/frontends/mt312.ko
/lib64/modules/3.18.140/kernel/drivers/mtd/maps/gpio-addr-flash.ko
/lib64/modules/3.18.140/kernel/drivers/staging-speakup/speakup.ko
/lib64/modules/3.18.140/kernel/drivers/usb/storage/ums/alauda.ko
/lib64/modules/3.18.140/kernel/drivers/usb/storage/ums-usbat.ko
/lib64/modules/3.18.140/kernel/drivers/video/uvesafb.ko
Do these matches mean that it was developed using Gentoo? How to tell exactly if a Linux distro was made using Gentoo?
